曲势场中的线性和非线性安德森局域化

Linear and nonlinear Anderson localization in a curved potential

Claudio Conti

摘要:

我们研究了在非线性和曲率存在下的无序诱导局域化。本文数值分析了具有聚焦类克尔相互作用项和高斯无序的弯曲雪茄形势中波包的时间分辨三维展开。我们报告一个自洽的分析理论,其中的随机性,非线性和几何形状由一个单一的尺度参数,并表明曲率增强本地化。

英文摘要:

We investigate disorder induced localization in the presence of nonlinearity and curvature. We numerically analyze the time-resolved three-dimensional expansion of a wave-packet in a bended cigar shaped potential with a focusing Kerr-like interaction term and Gaussian disorder. We report on a self-consistent analytical theory in which randomness, nonlinearity and geometry are determined by a single scaling parameter, and show that curvature enhances localization.
