The van der Waals (vW) long-range atom-surface interaction is often described as a dipole-dipole interaction, originating in the coupling between the quantum dipole fluctuations of an atom and the instantaneously induced fluctuations in the electrostatic image. Due to the finite light velocity, this atom-surface interaction is better understood in the more general frame of the Casimir-Polder theory...
The universal long-range van der Waals type atom-surface attraction was demonstrated to be susceptible of a resonant enhancement (with a possible change sign) when the virtual atomic emission can resonantly couple to a virtual absorption process in a surface mode. Presently, we investigate in the same cell the SR spectrum on the transition of interest for testing a resonant temperature dependence...
