[Cnqo] Talk by David Pekker, Tuesday June 24th

[Andrew Daley]

Hi Everyone,

On Tuesday June 24th at 10:00am, in the SUPA room (JA 8.13), Prof. David Pekker (University of Pittsburgh) will give an introduction to many-body localisation, and his recent work in this area. Prof. Pekker is a condensed matter theorist, with a strong background of collaborations with cold atoms experiments.

The title and abstract are listed below, and anyone who is interested is welcome to attend!

Very best regards,
Andrew

Title: Many-body localization

Abstract: In the past, condensed matter physicists have identified two types of insulators: band insulators and Mott insulators. In both types the Fermi surface lies inside a gap (either a band gap or an interactions induced gap) and hence there are no electronic states to carry a current. Recently, the interplay of disorder and interaction has been shown to result in a new type of insulator: the many-body localized insulator. Unlike band- and Mott-insulators that show Arrhenius conductivity at finite temperatures (due to thermal activation over the gap), the many-body localized insulator shows exactly zero conductivity. In my talk, I will describe the origin of this and other properties of this fascinating new type of insulator.
