AIMR Math Group On-line Seminar

#2 FY2020

 

Date : July. 7th (Tue) 2020 16:30-18:00

Venue: Zoom

Speaker: Chris Bourne (SUURI-COOL Sendai, AIMR, Tohoku University)
Title: Introduction to the mathematics of (aperiodic) topological materials

 

Abstract

Topological insulators and superconductors are materials whose physical properties can be characterised by abstract topological invariants.
Because topological invariants do not change under continuous deformations, the physical properties of topological materials are highly stable and have many potential applications. In this talk, I will give a basic introduction to the mathematical framework that makes these statements precise. By using a framework based on spectral theory and functional analysis, I will also indicate how we are able to study systems with disorder and aperiodicity.
