Fluctuation-induced dissipation in non-equilibrium moving systems

ORAL

Abstract

Quantum fluctuations in moving systems lead to nontrivial effects such as dissipation and radiation. We consider moving bodies---a single rotating object or multiple objects in relative motion---and derive the frictional force by using techniques from non-equilibrium statistical physics as well as quantum optics. The radiation to the environment is obtained as a general expression in terms of the scattering matrix which is a powerful analytical tool. We apply our general formulas to several examples of systems out of equilibrium due to their motion.
