不完全非广延统计的均衡统计力学

Equilibrium statistical mechanics for incomplete nonextensive statistics

A. S. Parvan, T. S. Biro

摘要:

在正则和微正则系综的不完全非广延统计的一般情况下,并在一个特殊的情况下,理想气体进行了探讨。通过对理想气体的精确分析结果表明,在热力学极限下,当$z=q/(1-q)$为广延状态变量时,不完全非广延统计量满足平衡态热力学的要求。统计系综的量子势是广义态变量的一阶齐次函数。在这种情况下,不完全非广延统计量等价于通常的Tsallis统计量。如果$z$是一个状态的强度变量,即熵指数$q$是一个普适常数,则违反了平衡热力学的要求。

英文摘要:

The incomplete nonextensive statistics in the canonical and microcanonical ensembles is explored in the general case and in a particular case for the ideal gas. By exact analytical results for the ideal gas it is shown that taking the thermodynamic limit, with $z=q/(1-q)$ being an extensive variable of state, the incomplete nonextensive statistics satisfies the requirements of equilibrium thermodynamics. The thermodynamical potential of the statistical ensemble is a homogeneous function of the first degree of the extensive variables of state. In this case, the incomplete nonextensive statistics is equivalent to the usual Tsallis statistics. If $z$ is an intensive variable of state, i.e. the entropic index $q$ is a universal constant, the requirements of the equilibrium thermodynamics are violated.
