摘要
利用平均场理论讨论了零温下具有长程库仑势的电子气体和短程相互作用的费米原子气体的铁磁相变问题,比较了两个模型中铁磁转变的不同性质.
The ground state phase transition from the paramagnetic state to the ferromagnetic state is studied via the mean-field approach both in electron gas with long range Coulomb interaction and atom gas with short range interaction.The properties of phase transition are obtained and the differences between the two models are compared.
