低于临界温度的弱相互作用玻色气体
Weakly interacting Bose gases below the critical temperature
摘要：
在有限温度场论的框架下，考虑了非零温度下均匀非理想玻色气体在临界温度以下的平衡态$T_C$。描述了一种算法，其中可以考虑一个可管理的图的子集，再加上与自由能的最小化相关的自洽条件，可以用来获得物理上合理的结果。
英文摘要：
We consider a homogeneous non-ideal Bose gas at nonzero temperature in equilibrium below the critical temperature $T_C$ in the framework of finite temperature field theory. An algorithm is described in which a manageable subset of diagrams can be considered which, coupled with a self--consistent condition related to the minimization of the free energy, can be used to obtain physically reasonable results.
