Statistical physics when the heat bath is large but finite

초록

In this paper we consider the thermodynamics when the heat bath is large but finite. We propose the deformed Boltzmann factor for a finite bath. With this modified Boltzmann factor we discuss some thermodynamics problems such as the classical oscillator, kinetic theory of an ideal gas, photon statistics and two-level system when the heat bath is large but finite. We compare our results with thermodynamics when the heat bath is infinite. (C) 2019 Elsevier B.V. All rights reserved.
