摘要：

The paper analyzes an approach to the generalization of the conventional Bose-Einstein statistics based on the nonadditive entropy of Tsallis. A detailed derivation of thermodynamic functions is presented. The calculations are made for the specific heat of two model systems, namely, the ideal three-dimensional gas obeying the nonadditive modification of the Bose-Einstein statistics and the system with linear excitation spectrum attempted as a qualitative approximation of liquid4He thermodynamics. © 2018 Fizika Nizkikh Temperatur.
