Abstract

We formulate fermionic versions, for any number of spatial dimensions, of the van der Waals and Casimir-Polder interactions and study their properties. In both cases, the systems we introduce contain localized “atoms”: two-level systems, coupled to a vacuum Dirac field. This Dirac field plays here a role akin to the electromagnetic field in the van der Waals case. In this context, bag model conditions for the Dirac field serve as the analog of the “mirror” in the Casimir-Polder effect. We found that, in this case, the resulting interaction is repulsive.

费米子范德华和卡西米尔-波德相互作用

我们对范德华和卡西米尔-波德相互作用的任何空间维度都制定了费米子版本，并研究了它们的性质。在这两种情况下，我们引入的系统都包含局域化的“原子”：与真空狄拉克场耦合的两能级系统。狄拉克场在这里的作用类似于范德华情况下的电磁场。在这种情况下，狄拉克场的袋模型条件相当于卡西米尔-波尔德效应中的“镜子”。我们发现，在这种情况下，产生的相互作用是排斥的。2025年由美国物理学会出版
