- Condensed matter physics is the most active field of contemporary physics and has yielded some of the biggest breakthroughs of the past century. But as rapidly as technology has advanced, scientists have only scratched the surface. Now for the first time, Jie Shan and Fai Mak, a married couple of physicists at Cornell University, have figured out a way to create artificial atoms in the lab, opening the door to a new era in research.

If you flush gasses with the appropriate temperature ,pressure with these systems on artificial will become real atoms because of free level cohesion at atomic scale
Jie Shan and Kin Fai Mak need to look deeper, these emergent properties are just a hint at an underlying structure. ;D
My question is, if they can simulate a series of oxygen atoms, can they actually produce oxygen from these structures?
Semiconductors are not alternative 2D materials, but they can be 2D materials.
@@nrgj.t669 NEVER ! the gluons are the same
I saw a video by Veritasium where he showed the Moiré lattice pattern, he held two transparent sheets of a honeycomb-ish pattern overlapping, and I remember seeing the different shapes and structures emerging, being completely fascinated! I got way too excited about it and felt silly. I'm a 30 year old woman, and I wanted to have these sheets myself to explore these patterns, they're beautiful. I knew there was something to it, and this video makes me very, very happy! Can't wait to see more from this research and channel, I'm a new subscriber.
It is exciting, nothing silly about recognizing that!
Moiré patterns have been used in art forever, but in my physics lectures, I show moiré patterns as a visual version of beat oscillation, and also as examples of a simple kind of interference pattern. (Think: holograms.) They are an excellent example of how there are larger patterns of patterns, and larger patterns still. This application is exciting, but also a natural next step in this direction of innovation. If we extended the hologram analogy, building a "holographic" graphene (or other material) pattern for a customized purpose would be exciting. (Think: super computer on a postage stamp.)
These ideas aren't new, but bringing them into reality IS new, and very, very exciting.
@@ezfzx Yes! I saw another video here on UA-cam a couple of hours ago, where this pattern was shown in a gradual simulation, showing all different patterns as it was turning. My first thought was; this looks like an oscillation/cymatics pattern! I also love the idea of showing things in a holographic way. Maybe a stupid question, but what if you layered three sheets of the pattern, would they show structures in 3D?
@@lis7742 It just gets more complicated, like adding more electron harmonics, and without precision control, there comes a chance that some of the sought after patterns would suffer from some slight destructive interference. Maybe an A.I. could manage it.
@@ezfzx I'm thinking the same, I can't wait to see how much an AI will immensely augment advancements in science (and many other areas). It's giving me hope for the future.
This channel is so high quality and criminally under-watched. Another A+ video
A lot of budget
True, this Channel is gold
It appears to suffer from an “old media” style that is going out of fashion.
Loads and loads of b and c roll shots that don’t allow the viewer to get a good visualisation of what’s being spoken about for 80% of the video.
Unfortunate because they do a decent job of reporting.
Wtf that’s at least one SSS too less. I feel confident this video is something to be proud of.
@@JMHynzie well u should consider if the inability to "get a good visualisation of what's being spoken about" is coming from you. I personally found the visualisation sufficient
Almost like they're making their own "fields" and then creating particles by putting different levels of energy into those "fields." Amazing.
Sounds hella scary when you say it like that
yes but the strenght of the chemical bonding of one of those artificial atoms its significantly weaker than that of an natural atom
Those energy levels are DIFFERENT than the natural ones
Pretty much making their own sandbox.. hmmm

@@kukulroukul4698 To be a top down and truly great physicist, you need to be a top down and truly great mathematician. Here's the CLEAR proof ON BALANCE.
ULTIMATE, CLEAR, BALANCED, INTEGRATED, IRREFUTABLE, AND MATHEMATICAL PROOF THAT ELECTROMAGNETISM/energy is gravity:
Consider what is TIME. E=MC2 is taken directly from F=ma, AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS the rotation of WHAT IS THE MOON matches it's revolution; AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE); AS the stars AND PLANETS are POINTS in the night sky ON BALANCE; AS TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Great. Consider WHAT IS THE EYE ON BALANCE !!! Great. c squared CLEARLY represents a dimension of SPACE ON BALANCE. GREAT. Consider TIME AND time dilation ON BALANCE. Consider what is THE SUN ON BALANCE. GREAT. Indeed, notice what is the orange AND setting Sun ON BALANCE !! ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). Consider WHAT IS THE EYE ON BALANCE !!!! GREAT ❤️❤️❤️❤️. Finally, what is lava IS orange; AND it is even blood red. Excellent.
By Frank DiMeglio
Consider what is the man (AND THE EYE ON BALANCE) who IS standing on what is THE EARTH/ground. Touch AND feeling BLEND, AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). Indeed, in identifying or considering what is THE EYE/EARTH balance, what is THE EARTH is ALSO BLUE. Great. NOTICE: Gravity cannot be shielded (or blocked) ON BALANCE. Magnificent !! Water flows downhill. Great.

So many developments like this seem hypey. But this one, dropping to 2D is such a beautiful simplification, lends itself to sane-time computer simulation. The moiré bit, again, beautiful. Reminds me a lot of X-ray crystallography, maybe similar potential for discovering how stuff works.
Couldn't have put it better
I'm wondeirng if this is what it was like for the square having the revelations about Flatland's existence
in one dimension i have some general understanding of their descriptions ...in the other dimension, I have no idea what they are talking about...

Never thought I would see Moire patterns being mentioned here. Absolutely amazing video!
I'd love to see a more in-depth video about the mechanics of how the stacked sheets create virtual atoms!
What are the limitations? Are there any conceivable functional/commercial uses (beyond research).
What an exciting development in physics research! I'm surprised this is the first I'm hearing of this technique/technology.
Funny enough, this is actually my field of research. I'm a PhD student in condensed matter experiment. The great part about these 2D materials is that we really don't know what their full capabilities are. We haven't yet realized all practical materials in 2D with proper study, so nobody knows what's still out there. Commercial uses range from solar panels that are factors more efficient than current panels, to faster computers, larger quantum computers, and many more. Realistically, this is one of the most fruitful fields of physics that still has a lot to be picked.
@@theflufffactor6060 Can the virtual atoms move around in their 2D matrix? Can they be combined into molecules?
@@GregConquest i think that as long as the moire pattern doesn't move, the Artificials Atoms (AA) won't move, AA are localized here. but creating an AA with an STM tip over a 2D materials (graphene), and moving the STM tip should give you mobile AA.
if 2 AA are close enough, their state shall interact giving you Artificial Molecule.
in the futur if we can control lot's of AA, we can simulate complex molecules and study their behaviour without doing very taxing computation, that's what we call quantu simulation i think (not sure)
@@GregConquest There is something called a semiconductor nanocrystal which people call an artificial atom, which can be assembled into artificial molecules. At least in my subsubfield, we don't care too much about moving them around in space. We focus on the electromagnetic properties of these low dimensional systems, not necessarily where they are.
In theory, you can control where these virtual atoms "are" by carefully configuring the real material stacks. In practice, these material systems are hard to make in the first place. Typically, if your project is on material AB, you would be over the moon if you can synthesize it and measure it. We are very much in the baby stages of this field. The Nobel Prize for the study of graphene was in 2010, just to put things in perspective.
Wait wait, I’m more thinking about combining those atoms in molecules and creating realistic matter? As in a form of very crude replicators from Star Trek is that possible? Would be awesome to be able to create actual matter from virtual Atoms! Imagine the possibilities if this becomes a reality!
Holy mother of god… virtual-atoms… I’ve seen it all now.
Wow. This feels like game changing research. New technology here we come. Material sciences are fascinating.
This was fascinating - great work!
Great video, thank you. Well scripted and visualized. You did a great job in explaining this concept clearly and concisely. Many video production creators don't get it right by doing what you did. Keeping it simple.
I love the realism of his attitude. He acknowledged that this work may not have much real world scaling, but the concepts themselves are what is important.
As another person commented..."WHOA!"
This sounds every bit as much a potential for experimental discoveries as the introduction of the microscope, electron microscope, telescope, oscilloscope, etc.
It may offer even more fundamental utility in linking geometry (2D planes, Moire patterns, alignments between planes, etc.) to the physics of materials
I don't think that has previously even been considered as an avenue for exploration
It has been considered, but, until recently, just hypothetical, waiting for the technology to catch up ... like so much innovation. When physicists get frustrated waiting for the future to arrive, they sometimes go write "hard" science fiction, a largely untapped resource for scientific inspiration. :)
@@ezfzx Did I hear 'Mars Trilogy' or 'Ender's Game' ?
@@gregparrott Perhaps! Some of the best "hard science" fiction, isn't always great fiction, since the authors are so excited by the science. But the science fans who understand it will eat it up. Some of the best ideas we've had for little under-grad research projects were inspired by works no one (outside of the science community) had ever heard of.
@@gregparrott Ender's Game is just god-tier
Imagine the capacity of a self-modifying microchip, real programmable electronics, not fake one like in FPGAs.
No one saw that potential, forget about superconductors. That would boost computers to another scale of power and give another spin to the wheel of Moore's law. (it is getting a bit slower , Moore's law is not dead and never will die, but the wheel can get slower and slower until a paradigm shift like this)
That if made into a working product would be a trillion dollar industry.
We could even call it metaelectronics, imagine the potential !
Can someone help me clear up my confusion?:
As I understand it, atoms are kinda defined by their number of protons, 1 for H, 2 for He, 3 for Li, etc. So why does changing the metric associated with electrons change the atom, and not just change it to a type of ion instead?
Also, as I understand it, an atom usually has the same amount of protons as neutrons, so are these created atoms special isotopes of the usual atoms?
What they have is a region in the 2D structure that behaves like an individual atom, but it's actually way bigger, so it's easier to measure. Atoms are defined by the number of protons, but their real behaviour and most characteristics are defined by how the electron cloud is distributed. That's why atoms in the same column of the periodic table have similar properties. When they change the voltage it changes how the simulated atom behaves.
@@tiagodasilva1124 appreciate the clear explanation!
@@ToriKo_ Yeah, I don't think there are actually any protons or neutrons in there. When they say "atom", it sounds like they've reproduced an electron cloud environment similar to what you'd find around an actual atom. Which is why it's "larger", because an actual atomic nucleus would pull those electrons in a LOT tighter.
According to Wikipedia. The amount of electrons in atom mirror the number of protons.
@@JasonB808 That is typically true. But these structures they are making are, near as I can tell, not complete atoms. They are clouds of electrons resonating the way they would if they were attached to an atom. It's very clever, but also a very VERY loose application of the phrase "artificial atom", which is no doubt causing the confusion.
Can someone explain something to me (not a trained scientist): how many of these "virtual atoms" can they manipulate at once? Are they able to scale the quantity up enough to make, for instance, clouds of virtual hydrogen, helium, etc?
Yeah and does this artificial atom go away when no more voltage is applied.
@@errgo2713 I don't think they are stable without the specific pressure, temperature, and energy conditions, as the quasiparticles are formed from those. I think you can see it as an electron liquid, where depending on those conditions it exhibits different, more bizarre quantum states of matter that are emergent from the interaction of many particles.
Also as I understand it, atoms are kinda defined by their number of protons, 1 for H, 2 for He, 3 for Li, etc. So why does changing the metric associated with electrons change the atom, and not just change it to a type of ion instead?
Also, as I understand it, an atom usually has the same amount of protons as neutrons, so are these created atoms special isotopes of the usual atoms?
this is what I wanted to ask
@@asdli6402 Because they aren't really atoms. It's a really common thing in condensed physics to do "simulations" of the real thing by using an absolutely different physical object, that on some level behaves similar to the thing you are studying. In this case, having read the article, it's not electrons that are orbiting "artificial atoms", it's "excitons" - a "particle" consisting of an electron+hole pair in different layers of the material. It is not really a particle in a physical sense, but it *behaves* like one, and if you are willing to accept it as a particle, it follows the regular Schrodinger's equation (except in 2D).
This isn't the first time condensed physics has done this - there are also so called "phonons", for example, that are quantum particles of sound waves - basically a particle representation of deformation waves travelling through a material, and they also behave like regular quantum particles if you look at them right.
What that Moiré lattice does is create potential wells for those "excitons", similar to how nucleus creates a potential well for an electron in the atom. This way, these excitons follow the Schrodinger's equation really similar to that of a real atom, so the effects you find with them can be applied to real atoms too. That's why they're called "virtual atoms" - they're not atoms in any real sense, there's no nucleus and there are excitons instead of electrons, but it's similar enough to be interesting. And yes, you can create lots of them - they're automatically "placed" at the nodes of the Moiré lattice, so as long as your sheet of material is big enough, you can get as many of them as you want.
Can they make 100x size artificial carbon atoms, then arrange them into giant artificial graphene sheets... then use those to make 10,000x size artificial artificial atoms, then....etc.
Beautifully animated, great job Quanta
These are good videos
This seems genuinely revolutionary
You can tell by how big they are smiling.
NOPE, its genuinely a bunch of nonsense, that's why they are smiling. No one has even seen a single Atom with any clarity, everything we think we know about atoms is pure speculation, No one has ever detected an Electron, a Proton or a Neutron, they are ASSSUMED to exist because or MODEL of the Atom says they ought to exist. Well, some don't agree with the current Model. Science is not about consensus.
So, they haven't created an atom from Electrons at all, they have not ever actually studied an electron, because they cant capture one or even if they did, nothing they could do could examine such an object.
Creating a sheet of graphene or similar only a couple of atoms thick, it would necessarily be practically invisible to an optical system. Remember an electron scanning microscope can only see a fuzzy blob that they think is an individual atom, so a material made from only two stacked is going to be too flimsy to hold together. Look at gold foil, it gets so thin that it cant be handled mechanically. it wafts away on the air currents if if gets too thin. And even then it no where near a few atoms thick.
So they are claiming to be able to make any element by just adding electrons one by one...
but Hydrogen has one electron and one Proton, but he said he added a single electron to make Helium, but Helium needs 2 Protons, so where did they second Proton come from?
There is no way to just "add" a single electron by "dialling up the voltage".
This is just like the quantum fake science they all rave about. All BS.
@@everythingisalllies2141 Let's assume everything you say is true. The device you are using to type all of this is based on storing billions of on/off states in matter using electrons. So even if we have never seen an atom or electron that doesn't really matter in any practical sense. We can build things in the real world with our models and they work in a consistent manner.
@@lucidvizion No, you ASSUME that the IC in my computer is working by storing little chinks of matter you called Electrons, because that is part of your imaginery MODEL of how electricity works. But SOMETHING is happening, but to claim its electrons is just your assumption. Truth is there is no way for you to prove that these electrons actually exist, you have never isolated one and presented it for inspection.
Artificial atoms based on Josephson junctions have been around for more than a decade now lol
another damn good video. I always waited for new videos from "Quanta Magazine"
Am I missing something? How does adding an electron to an atom change what element it is? It’s determined by proton number
Hence the word "Artificial" atom. It can still be used for a lot of research and application.
@@AnuragKmr26 it was never explained what they meant by that

Painting also is of a two dimensional world, and it is a made up world too.
This tightly controlled way of experimenting is like a painter's work to put the observer into a trance of awe.
The stacked plates as a lattice structure make me think of how we recognize patterns both in nature and in art.
To comment is also a way of looking with one idea at a time.
So being sleepy at the moment, I feel my own need to have some form of energy generating technology, but for my body now.
In that way, I would be better able to look with more control into how this breakthrough affects me as an observer.
" Art And Physics " by Leonard Schlane ( a Mill Valley neuro surgeon in California ) gives many examples of painter's who symbolically anticipated the next thing in Physics . My favorite was Picasso's " Demoiselles D Avignon " accurately symbolically depicting general relativity befor Einstein ever got it down on paper . Won't Artistic bio quantum Intelligence be a source of Cosmic Computer R. & D. In future terms .
@@brentdobson5264 how tf does a painting of four women depict general relativity
@@dedopest3305 Well runs like this if I recall the idea is Picasso intuitively energetically centered in on an experience that explores what happens / what one would see ..( painting symbolically ) should one just happen to approach viewing at the point of approaching one hundred eighty six thousand two hundred and forty six miles per second . It's here that evidently convential hard science says something to do with mass increasing and space forshortening ( things going flat and one supposes spreading out laterally ) and finally chroma having to shift to the grey scale . It's interesting to me there are a minimum and a maximum of four women ...seems to effectively concur with Richard Buckminster Fuller's minimum quantum four fold photon vertexia eddying tetrahedral unity one . To go forward with this idea Fuller one recalls talks about how this tetrahedron would turn inside out having approached the speed of light ( on the event horizon of a black hole one supposes ) . And why four women ? evidently Picasso liked the idea and in terms of Transcendental balance there would have to be two geometries here ...male straight line angular ergo tetrahedral center point to center point ( sphere to sphere ) unconscious reference abstraction ( fabstraction ) of female spherical genesis Geometry symbolized by the four fat broads in the picture wtf .
Props to the teams including postdoc and phd students in the research, because we know they are the unsung contributing heroes
astonishing! who wouldve guessed moire patterns could unlock this new world! bravo to Jie Shan, Fai Mak and their students
Have any undergraduate in Cornell worked on this project?
An interesting study, indeed. If they can control atoms more effectively, it could make huge improvements perhaps one day. My other point is that by adding electrons you are creating ions of hydrogen. To create heavier elements you need protons and neutrons. Still, it's a good method, IMO.
This channel covers such premiere topics.. with beautiful animation and natural narration.. it's a future 10M+ channel.
Does the vibrating thermal frequencies, cause the cold negative field, to circle around thermal energy, in forward maximum momentum velocity in resistance, to the cold fabric of space? Vibrations are thermal frequency. It is the momentum of the universe. It passes through the fabric of space in resistance producing outward pressure of force. Magnetic fields redirect thermal energy singularity frequencies into mass. Entanglement is magnetic fields of forced cycling circulation patterns of maximum momentum velocity in resistance. Harmonics of thermal energy redirected by resistance. Electricity is thermal energy singularity frequencies released from magnetic fields. It is the cold resistance of drag on mass as decay. It is resistance being dragged out of mass by thermal energy applied to magnetic fields disrupted, increasing drag out of equalization in mass. Thermodynamics are bombarding mass from all sides. Thermal energy is dark energy throughput space as space. Mass is space itself amplified by entanglement of magnetic fields holding mass together. Opposing forces coexist as space itself. Entanglement is two or more frequencies cycling in magnetic fields. Resistance creates magnetic fields of forced resistance to forward momentum creating cycling circulation patterns as mass.
Very interesting. Although I dislike the use of the term "artificial Helium" (chemical elements are defined by the number of protons in the nucleus), being able to create a simulacra of the outer electron shells using this technology would indeed recreate the array of chemical reactions that are possible. It would be very interesting to see this technology applied to replace catalysts in chemical reactions as the effect only needs to be temporary and does not remain in the product of the reactions.
I can’t wait until they start using this tech to start simulating instead of just single elements, compounds and complex molecules. We could actually start seeing how bonds form between different atoms and see how Adams move through space or stuff like that since I’m not too good at chemistry
"There are just too many of occurrences of low cost solutions to the tabasco sauce special theory of architectural patterns over the past year for it to be just a coincidence. You'll soon see you made the right choice about repulsive electromagnetic forces that correct topics of public importance and lemming-hypnosis. Giant gila monsters can attain sufficiently high velocities to overcome the effects of interacting quantum fields far more powerful than we can possibly think. But it will take awhile for hyper-dimensional lightning storms to promote dandelion tinctures. The Schrödinger equation in a panda furry suit gives a window of opportunity to study aquamarine spring water. Here is a scenario that can unfold to clear up any misconceptions about the photoelectric effect. Paint on, paint off. Wax the fence, wax the fence."

I had heard of their work but not read it yet, so I watched this video. I've watched Quanta videos in the past, and I think this one went a bit thin on the content. Based on the level of detail of the other videos on this channel, I think you could have had more details on their spintronic lab and the physics of the so-called "virtual atoms". Still, good video, now I need to go download those papers.
why does changing the number of electrons around that simulated atom change the atomic number? Does the simulated nucleus take on extra 'fake' protons and neutrons? Just adding electrons would just give you different hydrogen ions, no?
Why get a little girl - is that you, Grammarly Girl? - to narrate an article on unlocking 2d physics? It just sounds ridiculous. And quite annoying tbh!
Woah, this is science fiction made reality
@5:15 so now Einsteins theories are out the window? We have always been told creating new atoms (fusions) releases huge amounts of energy. Now we can do fusion without energy release? I smell another hyped tech advance here.
A while ago I read an article also about a similar moire experiments and where by accident was discovered that under a particular angle at room temperature electrons move without loss through the material. In the topology of materials and their setup there is still quite some exploration of new physics possible
could you plz link it in here?
You just pointed out a real world application. High temp superconducting.

If someone give me a time stamp when this video gets to the physics part and stops talking about some meet-cute love story, that would be great so I'm not wasting my time.

Finally we can create higher quality artificial food.
How can you change the properties of an element only by changing the number of electrons? Number of protons in an atom make it's characteristics and chemical properties. Whenever a Hydrogen atom is forced to get an electron, it changes to H+, not Helium. If you want to make it Helium, you need to add an additional proton to the nucleus. (Pls correct me if there's something wrong).
not absolutely sure but i will try an answer :
In their research they don't change the properties of an element, but the properties of Artif Atoms (AA). Chemical Properties of an Atom is linked to the n° of valence electron it currently has, property of AA is bound to the number of e- trapped in it.
Ion hydrogen with extra e- will be H- (not H+), it will have the same electrical configuration, 1s2, as Helium. so chemically speaking it should behave similarly as Helium.
By having 1 e-, the AA will act like it is an hydrogen atom (1s1 configuration), by having 6 e- it will act like an oxygen atom (i think so). By Making interacting two AA with 1e- and one AA with 6 e- , we should observe Artificial Molecule, with similar properties as a molecule of water H2O. meaning that in the futur, if you can control million of AA you can simulate the behaviour of a medicine on a part of a virus, without doing hours/weeks of simulation.
Emphasizing OP's "If you want to make it Helium, you need to add an additional proton to the nucleus." *100% correct.*
They developed a model for putative redox reactions, not transmutation.
Very neat for theoretical physicists. But chicanery for empirical chemists.
We taxpayers are allowing NSF and NIH to lead us down the slippery slope of theory because abstraction, PC's and programming are vastly more scalable and much cheaper financially than empiricism. Not that rival nation states are doing any better. [/rant]
Kindest regards, neighbours and friends.
One funny thing about chemistry is that when you add an electron to an atom of one element, you don't get a different element.
I was thinking the same.. Electrons alone don't change the chemistry significantly..
Maybe information is missed in the video ofr simplicity
From what i understand, since they are purely studying the effects of electrons, they are simulating groupings of them, and using that as the basis for a "virtual" hydrogen, helium, etc. atom. Not actually changing composition of anything, only changing the composition of the simulated virtual atom. Just like "If we want to simulate something with 2 electrons, we put 2 in" and helium being a typical example of something that would have 2.
@@dahZeee It was kind of a joke in deadpan, if you ask me. One is supposed to seek the grain(s) of truth within, I imagine. Myself I am reminded of how elements and ionic bonds organize in space by resonance and cooling. If it was two sheets of Boron Nitride (conveniently made-up combo by me) then I think you get two, maybe three, choices of good atom sims midway between plates.
So it's an analogue computer specifically designed to simulate simple condensed matter systems.
Correct me if I'm wrong,
So basically taking atoms to create artificial atoms that are easier to study 🗿😅
It's good that MSS doesn't have to work very hard to get their spies; we provide them willingly.
Some of the explanations are awfully hand-wavey given the video's word count.
Can we know properties of 119th element?
Hydrogen atom has one proton one electron and heleiem have 2 protons +2 neutrons +2 electrons I dont understand if they add 1 mode electron to hydrogen atom how are they going to add 2 neutron and 1 proton?
Shhh. You're just supposed to watch with an empty head and be amazed.
I saw answer in one comment, that they simulate atom core by passing current through Moiré superlattice
If they can study how electrons move from atom to atom, then it is the beginning.
When they discussed the Moire Super-lattice and artificial atoms, I was amazed. Never thought we could ever get so close to atomic transmutation!
Good jobs guys, we need more research on this, it could be huge, the equivalent to A.I singularity but for physics and chemistry!
agreed!
May I just say I am delighted how quickly this video followed the last!! I can’t get enough of this channel!!
This is the only time when science truly take a step forward : when people do it with Love
Using 2D things to predict 3d seems to be a recurring theme in life
Don't we need extra protons and neutrons?
20 years from now they will still be telling us quantum computing is coming soon
Very exciting stuff. The development of a room temp superconductor would be game changing :O
as a phd working on something similar, I really enjoyed watching this really well done video with great researchers. thanks Quanta for sharing and creating high quality content

youre never gonna sit me down in a room and tell me that just cuz its thinn its 2d lol
A new everything I like that !
Lets Go !When will we Realize
This
By changing the number of electrons we cannot change the element because it is the number of protons which determine the element for example a hydrogen atom is hydrogen because it has only one proton and by changing the number of electrons we can just change the charge on the atom like if we put 1 more electron to the hydrogen atom then it becomes negatively charged but it does not change to helium.

i thought adding protons changed the element not adding electrons what the hell is this
Hm, if thats a way to synthesize transuranium elements instead of what we have today - i'm all for it
why do you need to create artificial atoms? is there a shortage of real atoms?
Mind blowing, elegant, creativity.
woah we’re really getting into some rick and morty science over here
they could change the filling of e- and thus changed the chemistry of the element but wt about the number of protons and neutrons....how would that change as it is imp to change the no. of protons to change the element

This was bound to happen. Next up; 3D printing materials, atom by atom and then mass production.
And what if you combined this (2D) with Penrose tiling patterns and stacked those? What would the Moiré pattern look like?
Can Anything Be Truly Two Dimensional Especially When Most Things Not Even Atoms Or Fundamental Particles Exist Physically By Measure At The Planck Length?
Correct, I have been unable to find a single 2nd dimensional or 1st dimensional object. We are in a 3d universe of perpetual motion.
Non-motion generates nothing, nothing collapses, this collapsing generates folds, space, and time as we understand it, the folding of space it what we quantify as positive energy.
In reality, the 1st dimension is larger then the 2nd, which is larger then the 3rd. They coexist as ratios of one another, and are one and the same object.
Stuff like this blows my mind. Extremely interesting.
"I think this is just the beginning of it"
did you genuinely just say that electrons orbit
what the fuck
Absolutely wicked. Thank you for sharing.
Controlling artificial electron shells with voltage, using moire patterns of superimposed lattices?! That's insanely cool
LOOOL nice gibberish, they're grifting their $100k a year
Anything a Particle can do I can do Better, Sing it with me
Next, learn how to add protons and start turning lead into gold :) Thanks for the update!
i don't buy it. whatever they're talking about i'm getting the impression they're trying to make it sound a lot better than what it is.
same. someone's after some more grant money and it shows.
This time, like the other times,I've learned something.
Absolutely amazing!
Quanta , please don't let us alone with this long period of waiting :(
Thnak you Qunata
This is a phenomenal video
The term virtual atoms immediately makes me think if we can use these to simulate quantum computing without the extreme conditions needed to sustain single atom systems.
no
@@duality4y elaborate
So they've created artificial Atoms (artificially simulated atoms) within the stack of semiconductor material and when applying voltage an atom changes its properties from one atom element to another.
Marvelous!!!
Properties of elements are largely dependent on the electrons - at least that's how we are made to believe at large. But ignoring protons completely out of the scene and labelling it as an 'Artificial Atom' is something that is no syncing well personally. I might be wrong, never mind. Protons are the ones that balance the charge, keeping the atom in a neutral state.
This is what I felt when I saw the animation of electrons filling up an atom, without the mention of protons being a part of the nucleus.
They are like this generation Pierre and Marie Curie.
OMG! Mind-blown!
Quantum dots have been around since the late 90s tho
