超流相中的临界卡西米尔力:涨落效应

统计力学 2010-07-13 v5

摘要

我们考虑了4^4He薄膜在体λ\lambda点以下和以上的临界卡西米尔力。我们以微扰方式探索了平均场理论周围涨落的作用,并显著改进了Zandi等人[Phys. Rev. E {\bf 76}, 030601(R) (2007)]的平均场结果。我们得到的卡西米尔标度函数在T2.13 KT\lesssim 2.13~\text{K}时趋近于一个普适常数(ζ(3)8π-\frac{\zeta(3)}{8\pi})。

The term $\frac{1}{4b}\xi_0^4k_BT_\lambda$ at the Fig.2-caption in the published version should be read as $\frac{1}{4b\xi_0^4k_BT_\lambda}$
