Artigo Generalized quantum entropies(Elsevier, 2011-07-08) Anselmo, Dory Hélio Aires de Lima; Santos, A. P.; Silva, R.; Alcaniz, J. S.A deduction of generalized quantum entropies within the Tsallis and Kaniadakis frameworks is derived using a generalization of the ordinary multinomial coefficient. This generalization is based on the respective deformed multiplication and division. We show that the two above entropies are consistent with ones arbitrarily assumed at other contextsArtigo Kaniadakis statistics and the quantum H-theorem(Elsevier, 2011-01-17) Anselmo, Dory Hélio Aires de Lima; Santos, A. P.; Silva Junior, Raimundo; Alcaniz, J. S.A proof of the quantum H-theorem in the context of Kaniadakis’ entropy concept SκQ and a generalization of stosszahlansatz are presented, showing that there exists a quantum version of the second law of thermodynamics consistent with the Kaniadakis statistics. It is also shown that the marginal equilibrium states are described by quantum κ-power law extensions of the Fermi–Dirac and Bose–Einstein distributionsArtigo Non-Gaussian effects on quantum entropies(Elsevier, 2012-03-15) Anselmo, Dory Hélio Aires de Lima; Santos, A. P.; Silva Junior, Raimundo; Alcaniz, J. S.A deduction of generalized quantum entropies within the non-Gaussian frameworks, Tsallis and Kaniadakis, is derived using a generalized combinatorial method and the socalled q and κ calculus. In agreement with previous results, we also show that for the Tsallis formulation the q-quantum entropy is well-defined for values of the nonextensive parameter q lying in the interval [0,2].
