正则系综的组合起源

Combinatorial origins of the canonical ensemble

Kornelia Ufniarz, Grzegorz Siudem

摘要:

结合最速下降法的达尔文-福勒方法是统计物理学中许多模型的渐近描述的常用工具。在这项工作中,我们专注于达尔文-福勒过程的非渐近行为。通过使用基于贝尔多项式的组合方法,我们精确地解决了它。由于这种方法,我们还展示了典型模型与组合Lah和Stirling数的关系。

英文摘要:

The Darwin-Fowler method in combination with the steepest descent approach is a common tool in the asymptotic description of many models arising from statistical physics. In this work, we focus rather on the non-asymptotic behavior of the Darwin-Fowler procedure. By using a combinatorial approach based on Bell polynomials, we solve it exactly. Due to that approach, we also show relationships of typical models with combinatorial Lah and Stirling numbers.
