Block Lecture by Michael Fleischhauer - University of Kaiserslautern, Germany
Title: Topology in open many-body systems
Abstract:
Topological states of matter have fascinated physicists since a
long time. The notion of topology is however ususally associated
with ground states of (many-body)-Hamiltonians, which are pure.
So what is left of it at finite temperatures and can topological
protection be extended to non-equilibrium steady states (NESS)
of open systems? Can suitable observables be constructed that
preserve the integrity of topological invariants for mixed
states and what are measurable consequences of their existence?
Can we classify the topology of finite-temperature and NESS
using generalized symmetries?
