Herbert Spohn (TU Munich) : Generalised Gibbs ensembles for the Calogero fluid.

Abstract:  Over the past years there has been a lot of interest in investigating generalised Gibbs ensembles for integrable many-body systems. Besides some background, in my presentation I will discuss the classical fluid with the interaction potential 1/sinh^2, whose integrability was established by F. Calogero in the mid seventies. In particular I will explain the novel method based on the canonical transformation to scattering coordinates.
