Resonance Fluorescence of a Two-Level Atom Near a Rough Metal Surface.
Abstract
Surface-dressed optical Bloch equations are solved for a two-level atom near or adsorbed on a rough surface, which is modeled as a hemispheriod protrusion on a perfectly-conducting surface. Effects of the laser bandwidth are includes by means of a phase-diffusion model. The presence of the surface roughness generates a dephasing broadening mechanism on the adatomic resonance fluorescence spectrum, which can be strongly enhanced by plasma resonances depending on the shape of the hemispheroid. The dependence of the electrodynamics of the adatom on the adatom-hemispheroid distance is also evaluated. Keywords: Resonance fluorescence; Two level atom; Laser driven; Surface dressed; Rough metal surface; Adarom hemispheroid.
