Remark on the Second Principle of Thermodynamics

Statistical Mechanics 2017-08-23 v1

Abstract

All presently available results lead to the conclusion that nonextensivity, in the sense of nonextensive statistical mechanics (i.e., q1q \ne 1), does {\it not} modify anything to the second principle of thermodynamics, which therefore holds in the usual way. Moreover, some claims in the literature that this principle can be violated for specific anomalous systems (e.g., granular materials) can be shown to be fallacious. One recent such example is analyzed, and it is suggested how q1q \ne 1 distributions could in fact restore the validity of macroscopic time irreversibility, a cornerstone of our present understanding of nature.
