Kormos Márton (BME Elm. Fiz. tanszék):
Thermodynamics, transport, and fluctuations in the sine-Gordon model

The sine-Gordon model is a paradigmatic quantum field theory that provides
the low-energy effective description of many gapped 1D systems. Despite
this fact, its complete thermodynamic description in all its regimes was
lacking. In the talk, I will report the filling of this gap by deriving the
Thermodynamic Bethe Ansatz framework that captures the thermodynamics of
the model and serves as the basis of its hydrodynamic description. As a
first application, I will present results on the Drude weight
characterising the ballistic transport of the topological charge and
demonstrate that its dependence on the value of the coupling features a
fractal structure. I will also show recent results about the large-scale
fluctuations of the topological charge and current.
