非广延量子H定理

Nonextensive Quantum H-Theorem

R. Silva, D. H. A. L. Anselmo, J. S. Alcaniz

摘要:

考虑到非广延效应对量子熵$S^Q_q$的量子$H$定理的证明。结合对偶变换的$S^Q_q$的时间变化的正性意味着非广延参数$q$位于区间[0,2]中。它还表明,平衡态描述的量子$q$幂律扩展的费米-狄拉克和玻色-爱因斯坦分布。这些结果在广延极限下退化为标准结果,从而表明非广延熵框架可以与量子统计理论中包含的量子分布相协调。

英文摘要:

A proof of the quantum $H$-theorem taking into account nonextensive effects on the quantum entropy $S^Q_q$ is shown. The positiveness of the time variation of $S^Q_q$ combined with a duality transformation implies that the nonextensive parameter $q$ lies in the interval [0,2]. It is also shown that the equilibrium states are described by quantum $q$-power law extensions of the Fermi-Dirac and Bose-Einstein distributions. Such results reduce to the standard ones in the extensive limit, thereby showing that the nonextensive entropic framework can be harmonized with the quantum distributions contained in the quantum statistics theory.
