二次量子化场的安德森局域化:量子统计性质

Anderson Localization with Second Quantized Fields: Quantum Statistical Aspects

Clinton Thompson, Gautam Vemuri, G. S. Agarwal

摘要:

本文从理论上研究了非经典光场的安德森局域化,着重研究了局域光场的量子统计特性。我们证明,从本地化的光的平均强度的方差,以及站点到站点的相关性,本地化的光进行输入光的量子统计的签名。为了比较,我们也提出了结果与相干场统计和热场统计的输入光。我们的结果表明,由于介质的无序性,局域光的涨落会增强。我们还发现了局域光的超聚束,这可能有助于增强辐射与物质之间的相互作用。入射光的亚泊松统计的另一个重要后果是抑制输出处的总波动。最后,我们比较了高斯分布和矩形分布对无序的影响,并表明高斯无序加速了光的局域化。

英文摘要:

We report a theoretical study of Anderson localization of nonclassical light with emphasis on the quantum statistical aspects of localized light. We demonstrate, from the variance in mean intensity of localized light, as well as site-to-site correlations, that the localized light carries signatures of quantum statistics of input light. For comparison, we also present results for input light with coherent field statistics and thermal field statistics. Our results show that there is an enhancement in fluctuations of localized light due to the medium's disorder. We also find superbunching of the localized light, which may be useful for enhancing the interaction between radiation and matter. Another important consequence of sub-Poissonian statistics of the incoming light is to quench the total fluctuations at the output. Finally, we compare the effects of Gaussian and Rectangular distributions for the disorder, and show that Gaussian disorder accelerates the localization of light.
