摘要

The quantum thermodynamic functions of a hormonic oscillator coupled to a heat bath through velocity dependent coupling are obtained analytically.It is shown that both the free energy and the entropy decay fast with the temperature in relation to that of the usual coupling from.This implies that the veloeity-dependent coupling helps to ensure the third law of thermodynamics.
