量子混沌输运中时延的统计特性

Statistics of time delay in quantum chaotic transport

Marcel Novaes

摘要:

我们研究了时间延迟矩阵$Q$的统计性质的量子输运通过混沌腔的背景下,在时间反演不变性的情况下。首先,我们从随机矩阵理论的角度来处理这个问题,并得到精确的结果,提供了$Q$的任何多项式函数的平均值。然后,我们从半经典近似的角度考虑这个问题,获得一些依赖于能量的关联函数的整个扰动序列。使用这些关联函数,我们表现出协议之间的随机矩阵和半经典的方法的几个统计性质。

英文摘要:

We study the statistical properties of the time delay matrix $Q$ in the context of quantum transport through a chaotic cavity, in the absence of time-reversal invariance. First, we approach the problem from the point of view of random matrix theory, and obtain exact results that provide the average value of any polynomial function of $Q$. We then consider the problem from the point of view of the semiclassical approximation, obtaining the entire perturbation series for some energy-dependent correlation functions. Using these correlation functions, we show agreement between the random matrix and the semiclassical approaches for several statistical properties.
