Random matrix theory of sparse neuronal networks with heterogeneous timescales

open access: yesSciPost Physics
Training recurrent neuronal networks consisting of excitatory (E) and inhibitory (I) units with additive noise for working memory computation slows and diversifies inhibitory timescales, leading to improved task performance that is attributed to emergent

Random matrix theory and quantum chromodynamics [PDF]

open access: yes, 2017
Abstract This chapter was originally presented to a mixed audience of physicists and mathematicians with some basic working knowledge of random matrix theory. The first part is devoted to the solution of the chiral Gaussian unitary ensemble in the presence of characteristic polynomials, using orthogonal polynomial techniques.

PDE Methods in Random Matrix Theory [PDF]

open access: yes, 2020
This article begins with a brief review of random matrix theory, followed by a discussion of how the large-$N$ limit of random matrix models can be realized using operator algebras. I then explain the notion of "Brown measure," which play the role of the eigenvalue distribution for operators in an operator algebra.

Off-diagonal observable elements from random matrix theory: distributions, fluctuations, and eigenstate thermalization

open access: yesNew Journal of Physics, 2018
We derive the eigenstate thermalization hypothesis (ETH) from a random matrix Hamiltonian by extending the model introduced by Deutsch (1991 Phys. Rev. A 43 2046).

Replica approach in random matrix theory [PDF]

open access: yes, 2015
This article examines the replica method in random matrix theory (RMT), with particular emphasis on recently discovered integrability of zero-dimensional replica field theories. It first provides an overview of both fermionic and bosonic versions of the replica limit, along with its trickery, before discussing early heuristic treatments of zero ...

Optimized Tail Bounds for Random Matrix Series

open access: yesEntropy
Random matrix series are a significant component of random matrix theory, offering rich theoretical content and broad application prospects. In this paper, we propose modified versions of tail bounds for random matrix series, including matrix Gaussian ...
