掺杂石墨烯的增强Casimir效应

Enhanced Casimir effect for doped graphene

M. Bordag, I. Fialkovsky, D. Vassilevich

摘要:

我们分析了掺杂石墨烯的Casimir相互作用。为此,我们推导出一个简单的表达有限温度极化张量与化学势。据发现,掺杂导致强增强的卡西米尔力达到几乎$60\%$在相当现实的情况下。这一结果对于计划和解释卡西米尔测量应该是重要的,特别是考虑到未掺杂石墨烯的卡西米尔相互作用相当弱。

英文摘要:

We analyze the Casimir interaction of doped graphene. To this end we derive a simple expression for the finite temperature polarization tensor with a chemical potential. It is found that doping leads to a strong enhancement of the Casimir force reaching almost $60\%$ in quite realistic situations. This result should be important for planning and interpreting the Casimir measurements, especially taking into account that the Casimir interaction of undoped graphene is rather weak.
