Phys. Rev. E 61, 5994–5996 (2000)Momentum distributions for the quantum δ-kicked rotor with decoherenceReceived 19 May 1999; published in the issue dated May 2000 We report on the momentum distribution line shapes for the quantum δ-kicked rotor in the presence of environment induced decoherence. Experimental and numerical results are presented. In the experiment ultracold cesium atoms are subjected to a pulsed standing wave of near resonant light. Spontaneous scattering of photons destroys dynamical localization. For the scattering rates used in our experiment the momentum distribution shapes remain essentially exponential. © 2000 The American Physical Society URL:
