CMT Seminar - TODAY - Monday, November 24th - David Pekker, University of Pittsburgh - 11:30am, Smith Seminar Room

[Longbrake, Patricia]

Please join us TODAY for the Condensed Matter Theory Seminar presented by David Pekker from the University of Pittsburgh on Monday, November 24th at 11:30am in the Smith Seminar Room (1080 PRB).  The title and abstract are listed below.

"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 novel phase of matter.

Thank you,
