摘要: 实际气体粒子间都存在弱的相互作用,利用赝势法求出无外势时实际费米气体的能谱,导出了低温低密度下实际费米气体的化学势、压强、熵、内能和定容热容等物理量的解析表达式,探讨了粒子间相互作用对系统低温性质的影响.

关键词: 费米气体, 相互作用, 赝势法

Abstract: The weak interaction universally exists in actual gases, the analytical expressions of chemical potential, pressure, entrophy and heat capacity at a constant volume for actual gases in the absence of external potential are derived using total energy deduced by pseudo potential method, then based on the derived expressions, the effects of inter-particle interaction on the properties of Fermi gas systems are discussed.

Key words: Fermi gas, interaction, pseudo potential method
