Casimir-Polder interaction between an atom and a dielectric grating
Casimir-Polder interaction between an atom and a dielectric grating
We develop the scattering approach to calculate the exact dispersive Casimir-Polder potential between a ground-state atom and a rectangular grating. Our formalism allows, in principle, for arbitrary values of the grating amplitude and period, and of the atom-grating distance. We compute numerically the potential for a Rb atom on top …
