广义分子混沌假说与H定理:非广延统计力学的约束与修正问题

Generalized molecular chaos hypothesis and H-theorem: Problem of constraints and amendment of nonextensive statistical mechanics

Sumiyoshi Abe

摘要:

非常出乎意料的是,动力学理论被发现指定了在非广延统计力学中使用的平均值的正确定义。它表明,正常的平均值是一致的广义Stosszahlanesthetic(即,分子混沌假设)和相关的H定理,而在相关文献中广泛使用的q平均值则不是。在分析过程中,严格处理了具有有限截止因子的分布。在此基础上,对非广延统计力学的公式进行了修正。此外,肖尔-约翰逊定理,它支持使用的q-平均值,仔细重新检查,它发现,公理之一可能是不合适的系统内处理的非广泛的统计力学的框架。

英文摘要:

Quite unexpectedly, kinetic theory is found to specify the correct definition of average value to be employed in nonextensive statistical mechanics. It is shown that the normal average is consistent with the generalized Stosszahlansatz (i.e., molecular chaos hypothesis) and the associated H-theorem, whereas the q-average widely used in the relevant literature is not. In the course of the analysis, the distributions with finite cut-off factors are rigorously treated. Accordingly, the formulation of nonextensive statistical mechanics is amended based on the normal average. In addition, the Shore-Johnson theorem, which supports the use of the q-average, is carefully reexamined, and it is found that one of the axioms may not be appropriate for systems to be treated within the framework of nonextensive statistical mechanics.
