$d$维普适幂律势下理想玻色气体的热力学

Thermodynamics of ideal Bose gas under generic power law potential in $d$-dimension

Mir Mehedi Faruk

摘要:

在$d$维空间中,从宏观热力学势出发,系统地研究了囚禁在外部普适幂律势中的理想玻色气体的热力学性质.本文给出了玻色-爱因斯坦凝聚体的最一般条件和在一般幂律势存在下,在临界温度热容的不连续条件。讨论了这些物理量与外电势、粒子特性和空间维数的关系。本文所得到的较一般的结果,通过适当地选择幂律指数,使理想玻色系统的玻色-爱因斯坦凝聚简化为文献中的表达式和结论,从而给出了理想玻色系统的玻色-爱因斯坦凝聚的统一解释。

英文摘要:

Thermodynamic properties of ideal Bose gas trapped in an external generic power law potential are investigated systematically from the grand thermodynamic potential in $d$ dimensional space. The most general conditions for Bose-Einstein condensate and the discontinuous conditions of heat capacity at the critical temperature in presence of generic power law potential are presented in this manuscript. The dependence of the physical quantities on external potential, particle characteristics and space dimensionality are discussed. The more general results obtained in this paper presents an unified illustration of Bose-Einstein condensation of ideal Bose systems as they reduces to the expressions and conclusions available in the literature with appropiate choice of power law exponent.
