导电平面叠层的Casimir-Polder效应

The Casimir-Polder effect for a stack of conductive planes

Nail Khusnutdinov, Rashid Kashapov, Lilia M. Woods

摘要:

利用zeta函数正则化方法,考虑了原子与由无限薄平面组成的多层体系的Casimir-Polder相互作用.作为原型材料,每个平面由石墨烯片表示,其光学响应由恒定电导率或Drude-Lorentz模型电导率描述。各种分离的渐近表达式推导和数值计算相比。我们区分大原子/平面限制,其中延迟效应是突出的,和小原子/平面限制,其中典型的范德华系数被发现是依赖于石墨烯的数量和特征距离。不同原子和石墨烯导电性模型的计算能量提出了Casimir-Polder效应的基础科学,并提出了在实验上操纵这种相互作用的方法。

英文摘要:

The Casimir-Polder interaction between an atom and a multilayered system composed of infinitely thin planes is considered using the zeta-function regularization approach with summation of the zero-point energies. As a prototype material, each plane is represented by a graphene sheet whose optical response is described by a constant conductivity or Drude-Lorentz model conductivity. Asymptotic expressions for various separations are derived and compared to numerical calculations. We distinguish between large atom/plane limit, where retardation effects are prominent, and small atom/plane limit, where the typical van der Waals coefficient is found to be dependent on the number of graphenes and characteristic distances. The calculated energies for different atoms and graphene conductivity models brings forward the basic science of the Casimir-Polder effect and suggests ways to manipulate this interaction experimentally.
