摘要:

本文讨论了激光从拉长的原子玻色-爱因斯坦凝聚体散射时产生的超辐射光脉冲的时间统计特性。针对这一现象的早期阶段,我们分析了相应的概率分布及其与阈值光子数和耦合强度的标度行为。关于这些参数,我们发现数量之间的卡皮察狄拉克和布拉格制度的过渡期间,只有显着变化。本文还讨论了这些观测结果与布朗运动的可能联系。

英文摘要:

We discuss the passage-time statistics of superradiant light pulses generated during the scattering of laser light from an elongated atomic Bose-Einstein condensate. Focusing on the early-stage of the phenomenon, we analyze the corresponding probability distributions and their scaling behaviour with respect to the threshold photon number and the coupling strength. With respect to these parameters, we find quantities which only vary significantly during the transition between the Kapitza Dirac and the Bragg regimes. A possible connection of the present observations to Brownian motion is also discussed.
