Title:
One-point Functions in sinh-Gordon model and on-shell Yang-Yang Action
Speaker:
Abstract:
I shall explain the relation of the one-point functions for the the sinh-Gordon model with its generalized Gibbs ensemble. This relation leads to the definition of the on--shell Yang-Yang action which depends on the ""temperatures"" related to the higher integrals of motion. The one-point functions are given by the Hessian determinants of the Yang-Yang action.
