标题： Dispersion interaction of two graphene sheets

摘要： 通过改变零点真空能涨落来确定色散力的卡西米尔方法被应用于两个石墨烯片，在表面电导率的德鲁德模型近似下。 作为替代方法，使用了范坎彭求和方法。 在片之间的距离较小时和较大时都计算了力。 两种模型的结果非常相似。 具体来说，在大距离下，吸引力与距离的四次方成反比减少。 在短距离下，力是一个有限的吸引力。 当化学势较小时，力在约0.3纳米的距离处有一个最小值，然后增加，在约200纳米的距离处达到最大值，然后在大距离下与距离的四次方成反比减少。 当化学势显著大于1 eV时，不会观察到最小值。 显示英文摘要

摘要： The Casimir method for determining the dispersive force by varying zero vacuum energy fluctuations is applied to two graphene sheets in the approximation of the Drude model for surface conductivity. As an alternative, the Van Kampen summation method is used. The force is determined for small and for large distances between the sheets. The results of both models are quite similar. Precisely, at large distances, the attractive force decreases inversely proportional to the fourth power of the distance. At short distances, the force is a finite attractive one. With a small chemical potential, the force can have a minimum at distances of the order of 0.3 nm, then increases, reaches a maximum at distances of the order of 200 nm, and at large distances decreases inversely proportional to the fourth power of the distance. At a chemical potential of significantly more than 1 eV, a minimum is not observed.
