摘要:

计算了用非局域相互作用项描述的标量场与有限宽镜相互作用的Casimir能量。这些条款,其中包括量子效应,由于内部的物质场的镜子,近似通过一个本地扩展程序。作为这种展开的结果,真空场的有效理论出现了,它可以用广义$δ$势来表示。我们明确地计算了这些势的Casimir能量,并表明,对于某些特殊情况,有可能将它们重新解释为施加不完美的Dirichlet边界条件

英文摘要:

We calculate the Casimir energy for scalar fields in interaction with finite-width mirrors, described by nonlocal interaction terms. These terms, which include quantum effects due to the matter fields inside the mirrors, are approximated by means of a local expansion procedure. As a result of this expansion, an effective theory for the vacuum field emerges, which can be written in terms of generalized $δ$-potentials. We compute explicitly the Casimir energy for these potentials and show that, for some particular cases, it is possible to reinterpret them as imposing imperfect Dirichlet boundary conditions
