“…Note, that this perturbation approach has also been used to study for example the roughness effects for the Casimir force 23,24 . We remark that the perturbation theory can be applied as far as the rms of the surface profiles is the smallest lenght scale of the problem 25 . Then, by inserting the zeroth-order dyadic Green's function from 22 into the expression for the mean transmission coefficient in Eq.…”

The surface roughness correction to the near-field heat transfer between two rough bulk materials is discussed by using second-order perturbation theory. The results allow for estimating the impact of surface roughness to the heat transfer in recent experiments between two plates and between a micro-sphere and a plate (using the Derjaguin approximation). Furthermore, we show that the proximity approximation for describing rough surfaces is valid for distances much smaller than the correlation length of the surface roughness even if the heat transfer is dominated by the coupling of surface modes.

Ground-state van der Waals forces in planar multilayer magnetodielectrics

2005

View full text Add to dashboard Cite

Within the frame of lowest-order perturbation theory, the van der Waals potential of a groundstate atom placed within an arbitrary dispersing and absorbing magnetodielectric multilayer system is given. Examples of an atom situated in front of a magnetodielectric plate or between two such plates are studied in detail. Special emphasis is placed on the competing attractive and repulsive force components associated with the electric and magnetic matter properties, respectively, and conditions for the formation of repulsive potential walls are given. Both numerical and analytical results are presented.

Casimir-Polder interaction of atoms with magnetodielectric bodies

et al. 2005

Abstract. A general theory of the Casimir-Polder interaction of single atoms with dispersing and absorbing magnetodielectric bodies is presented, which is based on QED in linear, causal media. Both ground-state and excited atoms are considered. Whereas the Casimir-Polder force acting on a ground-state atom can conveniently be derived from a perturbative calculation of the atom-field coupling energy, an atom in an excited state is subject to transient force components that can only be fully understood by a dynamical treatment based on the body-assisted vacuum Lorentz force. The results show that the Casimir-Polder force can be influenced by the body-induced broadening and shifting of atomic transitions-an effect that is not accounted for within lowest-order perturbation theory. The theory is used to study the Casimir-Polder force of a ground-state atom placed within a magnetodielectric multilayer system, with special emphasis on thick and thin plates as well as a planar cavity consisting of two thick plates. It is shown how the competing attractive and repulsive force components related to the electric and magnetic properties of the medium, respectively, can-for sufficiently strong magnetic properties-lead to the formation of potential walls and wells.PACS. 12.20.-m Quantum electrodynamics -34.50.Dy Interactions of atoms and molecules with surfaces -42.50.Nn Quantum optical phenomena in absorbing, dispersive, and conducting media
