Energy spectrum of interacting gas: cluster expansion method

Hao-Dan Li, Shi-Lin Li, Yu-Jie Chen, Wen-Du Li, Wu-Sheng Dai

摘要:

本文将统计力学中的集团展开法转化为求解能量本征值的方法,计算了相互作用气体的能谱。我们得到了能量本征值的显式表达式,由此可以直接由粒子间势计算相互作用气体的本征值。作为一个例子,我们计算了具有软球势的相互作用气体的能谱。

英文摘要:

In this paper, we calculate the energy spectrum of interacting gases by converting the cluster expansion method in statistical mechanics into a method of solving energy eigenvalues. We obtain an explicit expression of the energy eigenvalue, by which we can calculate the eigenvalue of an interacting gas from the interparticle potential directly. As an example, we calculate the energy spectrum for an interacting gas with soft-sphere potentials.
