Abstract
We extend the Langevin dynamics so that particles can be exchanged wit h a particle reservoir. We show that grand canonical ensembles are rea lized at equilibrium and derive the relations of thermodynamics for pr ocesses between equilibrium states. As an application of the proposed evolution rule, we devise a simple model of Brownian motors driven by particle exchange.
