Study of the stability and paramagnetism of Fermi gas based on the semiclassical approximation
Tian Qing
Based on the semiclassical approximation,the energy spectrum of single fermion trapped in both gravitational field and strong magnetic field is given. By using Poisson's formula,the thermodynamic potential function of Fermi gas is derived. Furthermore,by using the thermodynamic relationships,the analytical expressions of the stability and magnetic susptibility of the system at low temperature are obtained. The influence mechanism of gravitational field on the thermodynamic properties of the system in the background of strong magnetic field is analysed by numerical simulation.
