我们考虑自由玻色子在网络(无限图)上跳跃。利用图上的随机游动给出了玻色-爱因斯坦凝聚的条件。对于周期晶格,我们也考虑了玻色子在周期势场中的运动,得到了玻色-爱因斯坦凝聚的判据。
We consider free bosons hopping on a network (infinite graph). The condition for Bose-Einstein condensation is given in terms of the random walk on a graph. In case of periodic lattices, we also consider boson moving in an external periodic potential and obatin the criterion for Bose-Einstein condensation.
