Topology Meets Quantum Mechanics - October 3, 2020

Sheng Ran, Washington University in St. Louis, presented this Saturday Science Lecture on October 3, 2020.
When abstract mathematical concepts find meaning in physical phenomena, revolutionary new theories of physics are often invented. such as the theories of general relativity and quantum mechanics. In the past few decades, a revolution has happened in our understanding of matter that was caused by the combination of quantum mechanics and the theory of topology. It has been discovered that when matter is topological, twists in their wave function bring up exotic properties, which might also have applications for the next generation of electronics. In this talk, Sheng Ran from Washington University in St. Louis will review basic concepts and the development of the topological understanding of matter.

I like the enthusiasm and clarity of the presentation. One question: In the discussion (around 18:04), the particle orbits are shown going one way (counter clockwise), but if the particle has negative charge, like an electron, then it will go clockwise instead?
