Dynamical localization is a localization phenomenon taking place, for example, in the quantum periodically driven kicked rotor. It is due to subtle quantum destructive interferences and is thus of intrinsic quantum origin. It has been shown that deviation from strict periodicity in the driving rapidly destroys dynamical localization. We report experimental results showing that this destruction is partially reversible when the deterministic perturbation that destroyed it is slowly reversed. We also provide an explanation for the partial character of the reversibility.
动力学局域化是一种例如在量子周期驱动的踢转子中发生的局域化现象。它源于微妙的量子相消干涉，因此具有内在的量子起源。已经表明，驱动中偏离严格周期性会迅速破坏动力学局域化。我们报告的实验结果表明，当破坏动力学局域化的确定性微扰缓慢反转时，这种破坏是部分可逆的。我们还对这种可逆性的部分特性给出了解释。
