    Gibbs' theorem for open systems with incomplete statistics

    Full text link
    Gibbs' theorem, which is originally intended for canonical ensembles with complete statistics has been generalized to open systems with incomplete statistics. As a result of this generalization, it is shown that the stationary equilibrium distribution of inverse power law form associated with the incomplete statistics has maximum entropy even for open systems with energy or matter influx. The renormalized entropy definition given in this paper can also serve as a measure of self-organization in open systems described by incomplete statistics.Comment: 6 pages, accepted to Chaos, Solitons and Fractal

    Bento \textit{et al.} [Phys. Rev. E 91, 022105 (2015)] state that the Tsallis entropy violates the third law of thermodynamics for q0q \leq 0 and 0<q<10<q<1. We show that their results are valid only for q1q \geq 1, since there is no distribution maximizing the Tsallis entropy for the intervals q0q \leq 0 and 0<q<10<q<1 compatible with the system energy expression.Comment: 2 pages, accepted in Phys.
