# Dyson’s disordered linear chain from a random matrix theory viewpoint

@article{Forrester2021DysonsDL, title={Dyson’s disordered linear chain from a random matrix theory viewpoint}, author={Peter J. Forrester}, journal={Journal of Mathematical Physics}, year={2021} }

The first work of Dyson relating to random matrix theory, "The dynamics of a disordered linear chain”, is reviewed. Contained in this work is an exact solution of a so-called Type I chain in the case of the disorder variables being given by a gamma distribution. The exact solution exhibits a singularity in the density of states about the origin, which has since been shown to be universal for one-dimensional tight binding models with off diagonal disorder. We discuss this context and also point…

Random discrete Schrödinger operators from random matrix theory

- Mathematics, Computer Science
- 2007

Random, discrete Schrodinger operators which arise naturally in the theory of random matrices, and depend parametrically on Dyson's Coulomb gas inverse temperature β are investigated and it is shown that as a function of β they undergo a transition from a regime of (power-law) localized eigenstates with a pure point spectrum for β < 2 to a regime for extended states with a singular continuous spectrum.
