我们解释了冷原子的动力学,这些原子最初在单色静止电磁波场中的磁光陷阱中被捕获和冷却。在大失谐极限下,系统被建模为非线性量子摆。我们表明,量子粒子的波包演化探测了量子摆中支持经典周期以及量子力学复兴和超复兴现象的参数状态。有趣的是,完整的重建,特别是量子复兴时的参数状态,与势高度无关。
We explain the dynamics of cold atoms, initially trapped and cooled in a magneto-optic trap, in a monochromatic stationary standing electromagnetic wave field. In the large-detuning limit, the system is modeled as a nonlinear quantum pendulum. We show that the wavepacket evolution of the quantum particle probes parametric regimes in the quantum pendulum that support the classical period and quantum-mechanical revival and superrevival phenomena. Interestingly, complete reconstruction, in particular the parametric regime at quantum revival times, is independent of the potential height.
