dc.description.abstract | We consider a paradigmatic model of a quantum Brownian particle coupled to a thermostat
consisting of harmonic oscillators. In the framework of a generalized Langevin equation, the memory
(damping) kernel is assumed to be in the form of exponentially-decaying oscillations. We discuss
a quantum counterpart of the equipartition energy theorem for a free Brownian particle in a thermal
equilibrium state. We conclude that the average kinetic energy of the Brownian particle is equal to
thermally-averaged kinetic energy per one degree of freedom of oscillators of the environment,
additionally averaged over all possible oscillators’ frequencies distributed according to some
probability density in which details of the particle-environment interaction are present via the
parameters of the damping kernel. | pl_PL |
