Topological States of Quantum Condensed Matter
-------------------------------------------------
Over the past three decades or more, it has slowly emerged that many unexpected properties of the ground states of certain condensed matter systems are protected by robust non-trivial topological properties of their quantum entanglement, with consequences such as characteristic inevitably-present edge states. Early work exposed such properties in one and two-dimensional systems and the discovery of 3D topological insulators finally completed dimensional coverage. Interest in topological states has grown as some of them are thought to be potential platforms for quantum information processing. I will describe some selected examples of topological states of matter and the history of their discovery. - Наука та технологія
Just wanna say WAW!!! Loved it!
@ 13:00 Dr. Haldane describes the half-spin entanglements in a way which sounds like the model of Ernest Sternglass. Details in his 1961 essay: "Relativistic Electron-pair Systems and the Structure of Neutral Mesons" published in the PHYSICAL REVIEW JOURNAL v.123 (1 July 1961);
Very informative ! Thank you !
Very Interesting Topic! Thank you.
Nice Lecture
Beginning at 1:06, the spin-singlet state should have a minus sign instead of a plus sign? (the plus sign belongs to the triplet state)
:) Joy
Every lecture on quantum physics explains certain phenomena using other complicated phenomena. Is there a book that can give a more visual representation of symmetry, topological materials and the like?
Prove to me the Earth is round by describing an experiment that only observes the sky. Also, please explain how we know how the galaxy is moving at 1.3 million miles per hour? In reference to what and why? I'm genuinely curious if anyone could please kindly tell.
What you really need is to learn how to read. But to put it mildly, condensed matter physics is not where you should begin if you don't understand classical mechanics
@@kanyinkeleko4498 If we were in front of each other right now you wouldn't be talking like that to me. I asked kindly for an experiment and an answer because I was genuinely wanting to know. All you gave me was a platter of your imperious character. Please be respectful to others. I apologize if I am not as intellectual or well studied as you are in the field of physics. I find science very interesting, but as Marine holding a machine gun for a living, I don't use it.
