Venue

Combination Room, 5th floor, AIMR Main Bldg.

Abstract

The 2016 Nobel prize for physics was a grant celebration of our understanding of topological phases and transition, part of which dates back to pioneering work of David Thouless and his collaborators when I became a graduate student of him 37 years ago. I was fortunate to be able to wetness and even participate the development of this topological theory of Chern insulators at the beginning of my career. In this talk, I will give an `inside look' of the topological Chern numbers, not only from my personal perspective, but also concentrating on its physical content, the Berry curvatures, to see how such topological and geometrical concepts have transformed our view of solid state physics.

About Tea Time Talk

AIMR’s Tea Time Talk is a kind of seminar aiming to promote exchange between world’s eminent researchers and young researchers at AIMR, held in a relaxed atmosphere at AIMR’s Friday Tea Time. The following researchers from around the world have given talks at this event so far, and participants have enjoyed discussion over a cup of tea.
