We numerically study the single particle localization and delocalization phenomena of an initially localized wave packet in the kicked Harper model (KHM) and Harper model subjected to quasiperiodic perturbation composed of M−modes. Both models are localized in the monochromatically perturbed case M = 1. KHM shows localization-delocalization transition (LDT) above M ≥ 2 as increase of the perturbation strength ǫ. In a time-continuous Harper model with the perturbation, it is confirmed that the… Expand


Dynamical Localization and Delocalization in Polychromatically Perturbed Anderson Map
In the previous paper[arXiv:1911.02189], localization and delocalization phenomena in the polychromatically perturbed Anderson map (AM) were elucidated mainly from the viewpoint ofExpand
Critical phenomena of dynamical delocalization in quantum maps: Standard map and Anderson map.
The self-consistent theory (SCT) of the localization is applied, taking a plausible hypothesis on the mean-free-path parameter which worked successfully in the analyses of the monochromatically perturbed QMs and comparing in detail the numerical results with the predictions of the SCT. Expand
From localization to anomalous diffusion in the dynamics of coupled kicked rotors.
The results show that quantum mechanics can deeply alter the regularity or ergodicity properties of a many-body-driven system. Expand
Drive-induced delocalization in the Aubry-André model.
The single particle delocalization phenomena of the Aubry-André (AA) model subjected to periodic drives is studied, exhibiting multifractality in the spectrum as well as in the Floquet eigenfunctions. Expand
Dynamical localization and the effects of aperiodicity in Floquet systems
We study the localization aspects of a kicked non-interacting one-dimensional (1D) quantum system subject to either time-periodic or non-periodic pulses. These are reflected as sudden changes of theExpand
The Aubry–André model as a hobbyhorse for understanding the localization phenomenon
We present a thorough pedagogical analysis of the single particle localization phenomenon in a quasiperiodic lattice in one dimension. Description of disorder in the lattice is represented by theExpand
Scaling properties of dynamical localization in monochromatically perturbed quantum maps: Standard map and Anderson map.
Dynamical localization phenomena of monochromatically perturbed standard map (SM) and Anderson map (AM), which are both identified with a two-dimensional disordered system under suitable conditions,Expand
Classical and quantum anomalous diffusion in a system of 2$\delta$-kicked Quantum Rotors
We study the dynamics of cold atoms subjected to {\em pairs} of closely time-spaced $\delta$-kicks from standing waves of light. The classical phase space of this system is partitioned into momentumExpand
