标题： Finite temperature Casimir effect for graphene

摘要： 我们采用石墨烯中准粒子的狄拉克模型，并计算悬浮石墨烯层与平行导电表面之间的有限温度卡西米尔相互作用。 我们发现，在高温下，该系统中的卡西米尔相互作用仅为相同距离分隔的两个理想导体之间相互作用的一半。 在这种极限下，单层石墨烯的行为完全类似于德鲁德金属。 特别是，TE模的贡献被抑制，而TM模的贡献则达到理想金属的值。 对实验可达到的中间温度和分离距离下卡西米尔相互作用的行为进行了详细研究。 我们还发现石墨烯物理中的两个基本常数之间存在有趣的相互作用：精细结构常数和费米速度。 显示英文摘要

摘要： We adopt the Dirac model for quasiparticles in graphene and calculate the finite temperature Casimir interaction between a suspended graphene layer and a parallel conducting surface. We find that at high temperature the Casimir interaction in such system is just one half of that for two ideal conductors separated by the same distance. In this limit single graphene layer behaves exactly as a Drude metal. In particular, the contribution of the TE mode is suppressed, while one of the TM mode saturates the ideal metal value. Behaviour of the Casimir interaction for intermediate temperatures and separations accessible for an experiment is studied in some detail. We also find an interesting interplay between two fundamental constants of graphene physics: the fine structure constant and the Fermi velocity.
