Mini-workshop on "The mathematics of interacting quantum systems in a random environment"
Organizers: Eric Cancès (ENPC, Paris) & Frédéric Klopp (Paris 6)

 

Robert Sims (Tucson, Arizona, USA): "On the Random XY Spin Chain"
Friday 14 June 2013, 11:30 - 12:15
Amphi Chaudron, Ecole Nationale Supérieure de Chimie, on the IHP campus

 

Abstract: We consider a collection of simple random spin systems (chains) and prove a strong form of dynamical localization. This localization is expressed in terms of a Lieb-Robinson bound (in
average) with zero velocity. We then discuss the consequences of this form of dynamical localization on (exponential) clustering in the ground state.
