Miniaturization is a major task for modern physics and for this atomic systems are promising candidates, e.g. for the implementation of quantum technologies. However, as atoms are trapped in a confined volume near macroscopic objects, phenomena like Casimir-Polder forces become important. In recent years, progress in experimental methods has revealed some not yet understood behaviors of these
interactions, especially with respect to dissipation in material composing the macroscopic body.
To gain more insight we investigate the contribution of the Foucault current modes on the magnetic Casimir-Polder interaction for a two-level atom in front of a conducting half-space. Both, a local Drude model and a non-local material model are considered for the description of the half-space’s permittivity. We analyze in detail the temperature dependence of some relevant thermodynamical properties of this contribution.
