Title: Topology of ultra-localized insulators

 
LPMMC, Room G421

 

Abstract: In this talk, I will argue that the topology of an insulator can be defined even when all eigenstates of the system are localized — an extreme case of Anderson insulators that we call ultra-localized. I will describe their bulk-boundary correspondence and show that ultra-localized systems are in many instances phases of matter not described by the known classification of topological insulators.
