I will discuss the derivation of nonlinear Gibbs measure from the thermal equilibrium state of an interacting Bose gas just above the Bose-Einstein phase transition. Our proof relies on a novel method to control the quantum variance which may be of general use.

This is joint work with M. Lewin and N. Rougerie.
