论文摘要
在零温度下，通过康沃尔 - jackiw-tomboulis有效的动作方法在改进的哈特里 - 折叠近似中，在零温度下在零温度下研究了稀释的bose气体中的casimir效应。我们的结果表明：（i）规范合奏中的Casimir能量和由此产生的Casimir力量与大规范合奏中的casimir能量和所产生的Casimir力； （ii）当两个平面墙之间的距离增加时，Casimir Energy和Casimir力量根据规范合奏中的一半力量定律，而不是大规范合奏中的整数功率定律。
The Casimir effect in a dilute Bose gas confined between two planar walls is investigated in the canonical ensemble at zero temperature by means of Cornwall-Jackiw-Tomboulis effective action approach within the improved Hartree-Fock approximation. Our results show that: (i) the Casimir energy and the resulting Casimir force in the canonical ensemble remarkably differ from those in the grand canonical ensemble; (ii) when the distance between two planar walls increases, the Casimir energy and Casimir force decay in accordance with a half-integer power law in the canonical ensemble instead of an integer power law in the grand canonical ensemble.
