Working in the framework of stochastic mechanics we propose a simple model, based on the hard-sphere gas approximation, for He II at T=0. The model seems to describe correctly the peculiar hydrodynamical behavior of He II near absolute zero and also provides good estimates for the critical velocities and the kinematic viscosity.

Abstract
Working in the framework of stochastic mechanics we propose a simple model, based on the hard-sphere gas approximation, for He II at T=0. The model seems to describe correctly the peculiar hydrodynamical behavior of He II near absolute zero and also provides good estimates for the critical velocities and the kinematic viscosity.
