Statistics of conductance and shot-noise power for chaotic cavities

H. -J. Sommers, W. Wieczorek, D. V. Savin

摘要:

我们报告的电导,$g$,和散粒噪声功率,$p$的统计分析研究的混沌腔与任意数量的$N_{1,2}$的通道在两个引线和对称参数$β= 1,2,4$。利用Selberg积分理论,计算了$g$的前四个累积量和$p$的前两个累积量.我们给出的电导和散粒噪声分布的解析表达式,并确定其精确渐近的边缘附近的线性顺序的距离的边缘。对于$0<g<1$,电导分布的幂律是精确的。所有结果也与数值模拟结果一致。

英文摘要:

We report on an analytical study of the statistics of conductance, $g$, and shot-noise power, $p$, for a chaotic cavity with arbitrary numbers $N_{1,2}$ of channels in two leads and symmetry parameter $β= 1,2,4$. With the theory of Selberg's integral the first four cumulants of $g$ and first two cumulants of $p$ are calculated explicitly. We give analytical expressions for the conductance and shot-noise distributions and determine their exact asymptotics near the edges up to linear order in distances from the edges. For $0<g<1$ a power law for the conductance distribution is exact. All results are also consistent with numerical simulations.
