一维长程关联随机势中局域化的增强

Enhancement of localization in one-dimensional random potentials with long-range correlations

U. Kuhl, F. M. Izrailev, A. A. Krokhin

摘要:

实验研究了一维弱随机势中局域化增强效应。我们的实验装置是一个单模波导与100个可调散射体周期性地插入到波导。通过测量每对散射体之间的间隔中的透射波和反射波的振幅,我们观察到当白噪声散射体被散射体的相关布置所取代时,局部化长度的强烈减小。

英文摘要:

We experimentally study the effect of enhancement of localization in weak one-dimensional random potentials. Our experimental setup is a single mode waveguide with 100 tuneable scatterers periodically inserted into the waveguide. By measuring the amplitudes of transmitted and reflected waves in the spacing between each pair of scatterers, we observe a strong decrease of the localization length when white-noise scatterers are replaced by a correlated arrangement of scatterers.
