带试探电荷的库仑气体中的统计关联

Statistical correlations in a Coulomb gas with a test charge

Henning Schomerus

摘要:

最近的一篇论文[Jokela等人,arxiv:0806.1491 2008年6月9日]包含关于库仑气体中的期望值的表面,该库仑气体与位于固定位置的附加电荷xi相互作用。在这里,我证明了猜测的表达式的有效性,并将其推广到某一类更高的累积量。该计算是基于随机矩阵理论的圆形酉系综中的统计平均值的类比,并利用单位圆上正交多项式的性质。

英文摘要:

A recent paper [Jokela et al, arxiv:0806.1491 9 June 2008] contains a surmise about an expectation value in a Coulomb gas which interacts with an additional charge xi that sits at a fixed position. Here I demonstrate the validity of the surmised expression and extend it to a certain class of higher cumulants. The calculation is based on the analogy to statistical averages in the circular unitary ensemble of random-matrix theory and exploits properties of orthogonal polynomials on the unit circle.
