摘要:
研究了随机边界对立方箱中相对论气体玻色-爱因斯坦凝聚临界温度的影响.在均匀分布、双模分布和高斯分布情况下,分别计算了临界温度与固定箱中的气体临界温度的比值,发现随机边界降低了系统的临界温度.相对于极端相对论情况,非相对论极限下的临界温度更低.

Abstract:
In this paper, the influence of the random boundaryon critical temperature of the Bose-Einstein condens at ion of relativistic gas in a cubic box is studied. Assume that the boundary of the box satisfies the uniform distribution, double mode distribution and Gaussi and is tribution, respectively, the ratio of the critical temperature to that of the gas in the fixed box is calculated. It is found that the random boundary reduces the critical temperature of the system. The critical temperature in then on relativistic limit is lower than that in the extreme relativistic case.
Key words:  Bose-Einstein condensation, Critical temperature, Random box, Relativistic Bose gas
