Superfluidity in the stochastic limit
Abstract
Description
In the present paper we outline the stochastic limit approach to superfluidity. The Hamiltonian describing the interaction between the Bose condensate and the normal phase is introduced. Sufficient in the stochastic limit condition of superfluidity is proposed. Existence of superfluidity in the stochastic limit of this system is proved and the non-linear (quadratic) equation of motion describing the superfluid liquid is obtained.
