Dear Colleagues,
 
Next Monday at 14:00 (sharp) the BME Exotic Quantum Phases seminar series 
continues with this talk:
 
Speaker: Balazs Pozsgai (BME)
Time: 14:00 (sharp), June 29 Monday
 
Title: Current operators and their mean values in integrable spin chains

Abstract: "Generalized Hydrodynamics (GHD) is a recent theory that describes 
the
large scale transport properties of integrable models. These systems
possess an infinite family of conservation laws, which constrain the
dynamical processes. As an effect, these systems support persistent
currents, and both the ballistic and diffusive part of the transport
can be described by theoretical methods. At the heart of GHD lies an
exact relation about the mean currents of the conserved quantities;
this was conjectured to be true rather generally, but for integrable
spin chains it was only proven in our papers. In this talk we explain
the main statements, we give a sketch of three different proofs, and
we also show a semi-classical interpretation of the results. The talk
is based on
