Toward Generalized Entropy Composition with Different q Indices and H-Theorem

Statistical Mechanics 2009-10-31 v4

Abstract

An attempt is made to construct composable composite entropy with different qq indices of subsystems and address the H-theorem problem of the composite system. Though the H-theorem does not hold in general situations, it is shown that some composite entropies do not decrease in time in near-equilibrium states and factorized states with negligibly weak interaction between the subsystems.
