Quantum Signatures of Anomalous Diffusion in Atom Optics

摘要: It is well established that classical chaotic motion suppressed by quantum mechanics. The paradigm theoretical system has been the ?-kicked rotor, where suppression manifests itself as dynamical localization. This effect saturation of momentum growth after break time, with a resulting exponentially localized distribution. Classical analyses this have also identified regimes anomalous diffusion, characterized “Levy-type” flights in phase space [1]. behavior considerably more complex than simple diffusion and attracted much interest recent years. was predicted to exhibit an increase localization length near regions [2], work predicts very large energy case, even for systems are far from semiclassical limit [3].
