Vacuum force on an atom in a magnetodielectric cavity

We demonstrate that the vacuum force on an atom embedded in a material cavity differs ubstantially 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. Toma\v s, Phys. Rev. A, accepted for publication ; arXiv: uant-ph/0502078]. This implies similar properties of the vacuum force between two atoms in a medium.
