Abstract

The reduced dynamics of a Brownian particle is discussed in single collision approach valid typically in dilute-gas environments. Our main purpose is a consistent account of quantum friction caused by local environmental interactions. We derive a Lindblad master equation whose generators are calculated from the differential cross-section of single collisions between the Brownian and the gas particles, respectively. The existence of thermal equilibrium for the Brownian particle’s state p is proved. Master equations proposed earlier are shown to be particular cases of our one.
