Phys. Rev. A 74, 023409 (2006) [4 pages]Self-driven nonlinear dynamics in magneto-optical trapsReceived 7 February 2006; published 23 August 2006 We present a theoretical model describing recently observed collective effects in large magneto-optically trapped atomic ensembles. Based on a kinetic description, we develop an efficient test particle method, which, in addition to the single-atom light pressure, accounts for other relevant effects such as laser attenuation and forces due to multiply scattered light with position-dependent absorption cross sections. Our calculations confirm the existence of a dynamical instability and provide deeper insights into the observed system dynamics. © 2006 The American Physical Society URL:
