Quantum Effects in the Collective Light Scattering from a Bose-Einstein Condensate
Abstract
In this paper I review the main features of the collective atomic recoil lasing (CARL) when the atomic medium is a Bose-Einstein condensate instead of the usual thermal gas. In a complete absence of thermal Doppler broadening the discreteness of the photon exchanged in the elementary scattering process becomes highly visible in CARL. Starting from the semi-classical CARL model in which the atomic motion is described classically, I discuss a simple quantum model for the self-consistent evolution of the matter-wave and the single mode radiation fields. A full quantum treatment of the linear evolution of the system shows that is possible to produce atom-atom or atom-photon entanglement in CARL. Ignoring the quantum statistics aspects of the problem, the temporal evolution of the condensate and scattered field in CARL is described, showing the main differences between the semi-classical and the quantum regimes.
