Mean-Field Description of Cooperative Scattering by Atomic Clouds
ATOMS(2023)
摘要
We present analytic expressions for the scattering of light by an extended atomic cloud. We obtain the solution for the mean-field excitation of different atomic spherical distributions driven by an uniform laser, including the initial build-up, the steady-state and the decay after the laser is switched off. We show that the mean-field model does not describe subradiant scattering, due to negative interference of the photons scattered by $N$ discrete atoms.
