一类具有增长参数的随机Jacobi矩阵的谱和动力学性质

Spectral and Dynamical Properties of Certain Random Jacobi Matrices with Growing Parameters

Jonathan Breuer

摘要:

本文研究了一类具有幂律增长的非对角项的随机Jacobi矩阵。由于随机性的增长比这些项的增长慢,因此可以使用应用于研究具有随机衰减势的薛定谔算子的方法。一个特殊的分析结果是存在的运营商与任意快速运输的谱测度是零维的。将所得结果应用于无限高斯$β$系综,分析了其谱特性.

英文摘要:

In this paper, a family of random Jacobi matrices, with off-diagonal terms that exhibit power-law growth, is studied. Since the growth of the randomness is slower than that of these terms, it is possible to use methods applied in the study of Schrödinger operators with random decaying potentials. A particular result of the analysis is the existence of operators with arbitrarily fast transport whose spectral measure is zero dimensional. The results are applied to the infinite Gaussian $β$ Ensembles and their spectral properties are analyzed.
