摘要: 一维谐振腔中的理想玻色气体没有相变,但是在低温下存在玻色一爱因斯坦凝聚体.在高温情况下,该体系的内能等于力一位移的乘积;关于微观状态数计算,传统的方法有所不足,本文给出了正确方法.

关键词: 玻色统计, 一维体系, 谐振腔

Abstract: A Boson gas in one-dimensional harmonic trap does not exhibit the phase transition, but at low temperature there is a macroscopic condensate in the ground state. At high temperature the internal energy is equal to the product of force and displacement. The number of microstates can not be computed with conventional method, and the correct way of enumeration is presented.

Key words: Bose statistics, one-dimensional system, harmonic trap
