Investigation of thermo dynamic prop erties of weakly interacting Fermi gas in weakly magnetic field by using the N-E-V distribution and pseudop otential method
基于低温下量子系统的相关实验多是在体积、能量和粒子数都可变的外场束缚下进行的事实,由体积、能量和粒子数可变的完全开放系统的统计分布(N-E-V 分布)研究了弱磁场中弱相互作用费米系统的热力学性质.首先求出了一般情况下由费米积分表示的内能和热容的解析表达式.在此基础上,又给出了在低温极限条件下内能与热容的解析表达式和数值计算结果,并将N-E-V 分布(粒子数密度变化)的结果与赝势法(粒子数密度不变)的结果进行了比较.结果表明: N-E-V 分布方法…查看全部>>
Based on the fact that most of low temperature experiments of quantum systems are explored in an external field on condition that the particle numbers, volumes and energies of systems may be changed, the thermodynamic properties of weakly interacting Fermi systems in weak magnetic field are studied by using the statistical distribution of the completely open system with variable particle number, volume, and energy (N-E-V distribution). Firstly, the analytica…查看全部>>
