多色扰动Anderson映射的动力学局部化与离域化

Dynamical Localization and Delocalization in Polychromatically Perturbed Anderson Map

Hiroaki S. Yamada, Kensuke S. Ikeda

摘要:

在先前的论文[PRE 101,032210(2020)]中,多色扰动Anderson映射(AM)中的定域和离域现象主要从扰动强度$ε$增加时的定域-离域转变(LDT)的观点来解释。在本文中,我们主要研究的现象对无序强度$W$的依赖性($W-$依赖性)在AM与一个特征的无序强度$W^*$。在完全局域化区域中,局域化长度的$W-$依赖性和$ε-$依赖性显示出与单色扰动情况下报告的特征行为相似的特征行为[PRE 97,012210(2018)]。此外,所获得的结果表明,即使对于$W$的增加,临界现象和临界指数被发现是相似的LDT中所引起的$ε$的增加。我们还研究了由这些参数引起的离域态的扩散性质。

英文摘要:

In the previous paper [PRE 101,032210(2020)], localization and delocalization phenomena in the polychromatically perturbed Anderson map (AM) were elucidated mainly from the viewpoint of localization-delocalization transition (LDT) on the increase of the perturbation strength $ε$. In this paper, we mainly investigate the dependency of the phenomena on the disorder strength $W$ ($W-$dependence) in the AM with a characteristic disorder strength $W^*$. In the completely localized region the $W-$dependence and $ε-$dependence of the localization length show characteristic behavior similar to those reported in monochromatically perturbed case [PRE 97,012210(2018)]. Furthermore, the obtained results show that even for the increase of the $W$, the critical phenomena and critical exponent are found to be similar to those in the LDT caused by the increase of $ε$. We also investigate the diffusive properties of the delocalized states induced by the parameters.
