无序势中物质波包的局域化

Localization of a matter wave packet in a disordered potential

Marie Piraud, Pierre Lugan, Philippe Bouyer, Alain Aspect, Laurent Sanchez-Palencia

摘要:

从理论上研究了一维无序势场中物质波包的安德森局域化。我们建立了一个包含初始物质波相空间密度和无序引起的谱展宽的解析模型。我们的方法预测的行为的本地化的密度分布显着更复杂的比一个简单的指数衰减。这些结果得到了大规模长时间数值计算的证实。他们为最近的超冷原子实验提供了新的线索,并可能影响他们的分析。

英文摘要:

We theoretically study the Anderson localization of a matter wave packet in a one-dimensional disordered potential. We develop an analytical model which includes the initial phase-space density of the matter wave and the spectral broadening induced by the disorder. Our approach predicts a behavior of the localized density profile significantly more complex than a simple exponential decay. These results are confirmed by large-scale and long-time numerical calculations. They shed new light on recent experiments with ultracold atoms and may impact their analysis.
