Atomic interaction effects in the superradiant light scattering from a Bose-Einstein condensate

TL;DR

This paper studies how atomic interactions influence superradiant light scattering in Bose-Einstein condensates, revealing that interactions cause dispersive effects in homogeneous samples and enhance decay in inhomogeneous ones.

Contribution

It provides a detailed analysis of atomic interaction effects on superradiant scattering, highlighting differences between homogeneous and inhomogeneous condensates.

Findings

Atomic interactions cause dispersive effects in homogeneous condensates.

In inhomogeneous condensates, interactions increase the decay of matter-wave gratings.

The study clarifies the role of atomic interactions in superradiant scattering dynamics.

Abstract

We investigate the effects of the atomic interaction in the Superradiant Rayleigh scattering from a Bose-Einstein condensate driven by a far-detuned laser beam. We show that for a homogeneous atomic sample the atomic interaction has only a dispersive effect, whereas in the inhomogeneous case it may increase the decay of the matter-wave grating.
