Entanglement in Disordered Quantum Many-Body Systems
Zusammenfassung: The introduction of disorder into a quantum system gives rise to a localized regime. For one-particle systems, described by random Schroedinger-type operators, the meaning of this is well understood and several essentially equivalent characteristics have been proven for broad classes of examples. Much less settled is the proper description of localization phenomena in interacting many-body systems. In this talk we will focus on upper bounds on quantum entanglement as a possible manifestation of many-body localization. In particular, we will discuss area laws for the entanglement of eigenstates as well as for the time evolution under quantum quenches in some simple models of quantum lattice systems.
Alle Interessierten sind hiermit herzlich eingeladen. Eine halbe Stunde vor dem Vortrag gibt es Kaffee und Tee im Sozialraum (Raum 448) im 4. Stock.
Treffpunkt zum Abendessen um 18.00 Uhr wird noch bekannt gegeben.
