In the present paper we discuss the stochastic limit approach to superfluidity. Starting from the usual Hamiltonian describing the interaction between the Bose condensate and the normal phase, we prove existence of superfluidity in the stochastic limit and deduce a non--linear (quadratic) kinetic equation describing the evolution of the density of superfluid liquid.

Abstract
In the present paper we discuss the stochastic limit approach to superfluidity. Starting from the usual Hamiltonian describing the interaction between the Bose condensate and the normal phase, we prove existence of superfluidity in the stochastic limit and deduce a non--linear (quadratic) kinetic equation describing the evolution of the density of superfluid liquid.File in questo prodotto:
