阈值附近随机带矩阵的特征多项式

Characteristic polynomials for random band matrices near the threshold

Tatyana Shcherbina

摘要:

本文继续了前人的工作,研究了一维高斯厄米特随机带阵$n\times n$的特殊情况下,当阵元的协方差由矩阵$J=(-W^2\triangle+1)^{-1}$决定时,特征多项式的第二关联函数的性质。应用传输矩阵方法,研究了带宽$W$与门限$\sqrt{n}$成正比的情况

英文摘要:

The paper continues previous works which study the behavior of second correlation function of characteristic polynomials of the special case of $n\times n$ one-dimensional Gaussian Hermitian random band matrices, when the covariance of the elements is determined by the matrix $J=(-W^2\triangle+1)^{-1}$. Applying the transfer matrix approach, we study the case when the bandwidth $W$ is proportional to the threshold $\sqrt{n}$
