The David Olive Distinguished Lecture, March 2023, by Professor Sean Hartnoll (DAMTP, Cambridge)
Antimatter- from Physics to Application. Professor Mike Charlton, Physics Colloquium 08 03 2023
Переглядів 291Рік тому
The topic of antimatter is introduced by recalling its prediction and discovery in the 1930’s, and a brief history of the subject is given. Positrons have since found numerous applications in atomic and materials science, engineering and medicine, often based upon their annihilation with electrons, their matter equivalent particle. What makes this antiparticle useful as a probe is discussed, an...

    Interesting to know so much about magnetic monopoles, with bonus knowledge about color fields and how glueballs can be massive as they are magnetic flux lines. What impressed me is the honesty with which Dirac's theory is making new waves and the mathematics involved sounded right and logical. In ten years we may get proper window to 'string' theory.

    Seems like if we can see electric monopoles when an electron get separated from its proton buddy, then, ignoring everything that could outlaw it, wouldn't you get a magnetic monopole if you had a sun mass of only electrons or only protons? A large mass containing only negative charges or only positive charges? How much electric charges would you need to jump say the light year that separate the two opposite-charge bodies, even if there was nothing between them? How far could opposite-poled magnetic molopoles could see each others? And what if we had a pair of monopoles escaping each others faster than light in an expanding universe, could they still influence each other via some materials in between? Could we have a black hole worth of a monopole? Could you feel them outside of the event horizon? I am probably completely lost, but it's nevertheless fun to try to imagine. Let's keep listening. I taught it is not the electron that goes through both slides, but the wave function, that 'knows' the probability of all possible paths. When the electron hits the wall, only then nature chooses where the electron will appear, based on the probabilities dictated by the wave function. I.e. Nature choose based on the possible paths, since she knows the probability of them all. Sounds like a computer to me. 46:46, are you saying that the 3 quark colors are involved in the -1/3 electric charge of the down quark and the +2/3 of the up quark? The strong force colour dictates the electric charge? That would be odd, considering that the 3 quarks in a proton /neutron keep exchanging colors, witch obviously don't affect the electric charges. I am missing something here. And the color is involved in the magnetic (moment?)? I always found weird the 1/3, 2/3 charge, I tought a quanta of something had to be an integer of sort. 1:00:28 Does the idea of monopole/antimonopole extend to the magnetic pole/antipole?

One side matter, the other antimatter. Am inflow here is an outflow from there. Clockwise here is counterclockwise there. The actual form of the manifold is not spherical. It is a single sided closed surface which has two regions separated by a moment of torsion. Each the perfect reciprocal of the other.

      Interesting idea. I don’t know much but a proton and an electron attract each other but don’t simply collapse and instead form a hydrogen atom. They don’t collapse probably because the attraction has quantum properties. Maybe a north and south monopole would do the same. I guess that’s also why gravity is interesting and right now general relativity is incompatible with quantum mechanics.

      Point here is that there is such a thing as electric charge, coming in two varieties (positive and negative) and we could call an electric charge an "electric monopole". Put these two charges at the opposite ends of a rigid rod and you have an ``electric dipole" with an ``electric dipole moment". Remove the rod and allow them to collapse into each other, you get a neutral atom like object with or without an electric dipole moment (e.g. the Hydrogen atom is made of a positive and negative charge which can be in the ground state with zero electric dipole moment or an excited state with non-zero electric dipole moment). With magnetism there is no such thing as a magnetic charge, although there is such a thing as a magnetic dipole (that would be any magnet). There is no fundamental natural or mathematical obstruction to having a magnetic monopole, except that we haven't seen any in Nature ! So magnetic monopoles (or magnetic charges) if they existed could bind together to form atoms or magnetic dipoles like their electric counterparts. As you note there is such a thing as "gravitational charge" or "gravitational monopole" -- we call it "mass". But mass comes with only one sign -- there is no such thing as "negative mass". So in gravity we don't get gravitational dipoles (very unlike electricity and magnetism)!

    So as I explained to the math guy, you won't find a magnetic monopole for the verse. That's an impossibility. It's not magnetically charged. The EMFS we observe are manufactured they are not a eternal force. We know this because we are inside several EMF bubbles the original being from our blacksphere. Now when you look across the verse you will see lots of poles. Each galaxy should have its own. This is where physicist make the first mistake I believe. Thinking the matter verse is part of the infinite ♾️ space. This is a mistake and is another reason most theory fail. Separation of these 2 entities is an absolute must if you want to find the correct theory I believe. So magnetic monopoles everywhere except for the infinite ♾️ space. We're in space not of the space. Thanks for reading and I hope this helps. Peace ✌️ from Canada eh.

    if you have a sphere then pin to the surface magnets that the south pole faces in north faces out is that then one pole?

      That’s good, but no. Where does the inward flux go? The lines come out somewhere

    dig two hole in the earth one small one big what has more mass ? is there mass to a hole?

    just because a black hole gets bigger does not mean its mass is getting bigger just means the hole is bigger so that's less, not more?

    It amazes me that many teachers of magnetism do not understand magnetic filed lines. A) the paper with filings on it obviously is a cross section of a magnets field , so the true shape is a toroid. ( lines would actually therefore be shells not lines ) B ) the iron filings collect immediately into looping lines because each particle becomes a small magnet itself , all the particles orient and form the lines, The field its self does not have "lines" these are an interaction between the field and the filings. So there are no actual lines around a free standing bar magnet and there is no flow in that field , which the term "Flux" might suggest. The "Lines of Flux" and "field density" is contextual to calculation purposes so we can quantify magnets and put them to use in engineering and science .

    what happens when one twists a long bar magnet into an odd PI Mobius?

    Spinning disk magnets produce massive imbalance of charge. Your fascination with electrons is based on the theory the core of the earth is made from magnetite. New evidence shows it's oxygen & aluminium, which produce larger particles.
