We study the destruction of dynamical localization experimentally observed in an atomic realization of the kicked rotor by a deterministic Hamiltonian perturbation, with a temporal periodicity incommensurate with the principal driving. We show that the destruction is gradual, with well-defined scaling laws for the various classical and quantum parameters, in sharp contrast to predictions based on the analogy with Anderson localization.
我们通过确定性哈密顿微扰研究了在踢转子的原子实现中实验观察到的动力学局域化的破坏，该微扰具有与主驱动不匹配的时间周期性。我们表明，这种破坏是渐进的，对于各种经典和量子参数具有明确的标度律，这与基于与安德森局域化类比的预测形成鲜明对比。
