Nonextensive thermostatistics for heterogeneous systems containing different $q$'s

Statistical Mechanics 2007-05-23 v2

Abstract

The nonextensive statistics based on Tsallis entropy have been so far used for the systems composed of subsystems having same qq. The applicability of this statistics to the systems with different qq's is still a matter of investigation. The actual difficulty is that the class of systems to which the theory has been applied is limited by the usual nonadditivity rule of Tsallis entropy which, in reality, has been established for the systems having same qq value. In this paper, we propose a more general nonadditivity rule for Tsallis entropy. This rule, as the usual one for same qq-systems, can be proved to lead uniquely to Tsallis entropy in the context of systems containing different qq-subsystems. A zeroth law of thermodynamics is established between different qq-systems on the basis of this new nonadditivity.
