关于量子力学中一个有趣而重要的模型II。热力学描述

About One Interesting and Important Model in Quantum Mechanics II. Thermodynamic Description

Yuri G Rudoy, Enock O Oladimeji

摘要:

本文详细研究了单重粒子的非相对论性量子力学中最有趣的模型之一,由G. Poeschl和E. Teller在1933年提出的势函数、波函数和能谱的动力学分析的出发点是由同一作者继续进行的。这些结果在非零温度情况下的推广包括模型的配分函数的近似计算,以及Massieu Planck热力学势及其最重要的导数,即内能、热容和压力。由于缺乏全温度下势的精确统一表达式,对结果的分析分别在低温区和高温区进行。

英文摘要:

In this paper the detailed investigation of one of the most interesting models in the non relativistic quantum mechanics of one massive particle i.e., introduced by G. Poeschl and E. Teller in 1933 is continued; the starting point of dynamic analysis for potentials, wave functions and energy spectrum was carried on by the same authors in the paper. The generalization of these results on the case of nonzero temperature includes the approximate calculation of the partition function of the model and then also the Massieu Planck thermodynamic potential and its most important derivatives, i.e. internal energy, heat capacity and pressure. The analysis of the results is carried on separately for low and high temperature regions because of the lack of exact unifying expressions of the potential at all temperatures.
