Abstract

For the describing of a system under the combined quantum and thermal influences, it is offered two approaches each of them is a thermofield analogue of Clausius'classical and Einstein's statistical thermodynamics accordingly. We call them as Thermofield Thermodynamics and Thermofield Statistical Thermodynamics. We start from the thermofield vacuum and make a consent between basic notions of the quantum mechanics and thermodynamics. We suppose to consider the thermofield vacuum as an effective thermobath and ground stationary state as an thermal equilibrium state. On this ground we introduce such notions as effective temperature and effective entropy and get possibility to describe systems under combined quantum and thermal influences.
