Strong geometry dependence of the Casimir force between interpenetrated rectangular gratings

Mingkang Wang, L. Tang, C. Y. Ng +6

Quantum fluctuations give rise to Casimir forces between two parallel conducting plates, the magnitude of which increases monotonically as the separation decreases. By introducing…

Casimir-Polder Shift and Decay Rate in the Presence of Nonreciprocal Media

Sebastian Fuchs, J. A. Crosse, Stefan Yoshi Buhmann

We calculate the Casimir-Polder frequency shift and decay rate for an atom in front of a nonreciprocal medium by using macroscopic quantum electrodynamics. The results are a genera…

Coincident count rates in absorbing dielectric media

J. A. Crosse, Stefan Scheel

A study of the effects of absorption on the nonlinear process of parametric down conversion is presented. Absorption within the nonlinear medium is accounted for by employing the f…

Thermal Casimir-Polder shifts in Rydberg atoms near metallic surfaces

J. A. Crosse, Simen Å. Ellingsen, Kate Clements +2

The Casimir-Polder (CP) potential and transition rates of a Rydberg atom above a plane metal surface at finite temperature are discussed. As an example, the CP potential and transi…

Effective nonlinear Hamiltonians in dielectric media

J. A. Crosse, Stefan Scheel

We derive an effective Hamiltonian for the nonlinear process of parametric down conversion in the presence of absorption. Based upon the Green function method for quantizing the el…

Atomic multipole relaxation rates near surfaces

J. A. Crosse, Stefan Scheel

The spontaneous relaxation rates for an atom in free space and close to an absorbing surface are calculated to various orders of the electromagnetic multipole expansion. The sponta…
