磁介质腔中原子的真空力

Vacuum force on an atom in a magnetodielectric cavity

M. S. Tomas

摘要:

我们证明,根据最近提出的洛伦兹力的Casimir效应的方法,嵌入在材料腔中的原子上的真空力与腔介质中的原子上的力有很大的不同。作用在嵌入原子上的力是我们熟悉的(范德华力和卡西米尔-波尔德力)类型,然而,腔介质比通常认为的更强烈地改变了这种力。作用在腔介质中原子上的力是一种介质辅助力,它具有一些不寻常的性质,这一点最近已得到证实[M。S. Tomas,Phys.Rev.A71,060101(R)(2005)]。这意味着介质中两个原子之间的真空力具有类似的性质。

英文摘要:

We demonstrate that, according to a recently suggested Lorentz-force approach to the Casimir effect, the vacuum force on an atom embedded in a material cavity differs substantially from the force on an atom of the cavity medium. The force on an embedded atom is of the familiar (van der Waals and Casimir-Polder) type, however, more strongly modified by the cavity medium than usually considered. The force on an atom of the cavity medium is of the medium-assisted force type with rather unusual properties, as demonstrated very recently [M. S. Tomas, Phys. Rev. A 71, 060101(R) (2005)]. This implies similar properties of the vacuum force between two atoms in a medium.
