We consider a system of quantum particles at positive temperature. Particles are located in a large box and subjected to an electric potential which is periodic in the whole space. We prove the existence of a surface term for the grandcanonical pressure. Cooperation with Søren Fournais, Laboratoire de Mathématiques, université de Paris Sud, France.
