Random Matrix Theory Predictions of Dominant Mode Rejection Beamformer Performance

open access: yesIEEE Open Journal of Signal Processing, 2022
Adaptive beamformers use a sensor covariance matrix estimated from data snapshots to mitigate directional interference and attenuate uncorrelated noise.

Random matrix theory for complexity growth and black hole interiors

open access: yesJournal of High Energy Physics, 2022
We study a precise and computationally tractable notion of operator complexity in holographic quantum theories, including the ensemble dual of Jackiw-Teitelboim gravity and two-dimensional holographic conformal field theories.

Abnormal Node Location Algorithm for WSN Based on Random Matrix Theory [PDF]

open access: yesJisuanji gongcheng, 2020
Existing abnormal node detection methods for Wireless Sensor Network(WSN) have difficulty in obtaining the statistical model,and the computational cost of large-dimensional data is high.To address the problem,this paper introduces the Random Matrix ...

Towards large scale continuous EDA: a random matrix theory perspective [PDF]

open access: yes, 2013
Estimation of distribution algorithms (EDA) are a major branch of evolutionary algorithms (EA) with some unique advantages in principle. They are able to take advantage of correlation structure to drive the search more efficiently, and they are able to ...

Characteristic polynomials of complex random matrix models [PDF]

open access: yes, 2002
We calculate the expectation value of an arbitrary product of characteristic polynomials of complex random matrices and their hermitian conjugates. Using the technique of orthogonal polynomials in the complex plane our result can be written in terms of

Supersymmetric SYK model and random matrix theory

open access: yesJournal of High Energy Physics, 2017
In this paper, we investigate the effect of supersymmetry on the symmetry classification of random matrix theory ensembles. We mainly consider the random matrix behaviors in the N = 1 $$ \mathcal{N}=1 $$ supersymmetric generalization of Sachdev-Ye-Kitaev

Quasiclassical Random Matrix Theory [PDF]

open access: yesPhysical Review Letters, 1996
We directly combine ideas of the quasiclassical approximation with random matrix theory and apply them to the study of the spectrum, in particular to the two-level correlator. Bogomolny's transfer operator T, quasiclassically an NxN unitary matrix, is considered to be a random matrix.

The Lenard recursion relation and a family of singularly perturbed matrix models [PDF]

open access: yes, 2015
We review some aspects of recent work concerning double scaling limits of singularly perturbed Hermitian random matrix models and their connection to Painlevé equations. We present new results showing how a Painlevé III hierarchy recently proposed by the

Skew-orthogonal Laguerre polynomials for chiral real asymmetric random matrices [PDF]

open access: yes, 2010
We apply the method of skew-orthogonal polynomials (SOP) in the complex plane to asymmetric random matrices with real elements, belonging to two different classes. Explicit integral representations valid for arbitrary weight functions are derived for the

Dynamical quantum phase transitions from random matrix theory [PDF]

open access: yesQuantum
We uncover a novel dynamical quantum phase transition, using random matrix theory and its associated notion of planar limit. We study it for the isotropic XY Heisenberg spin chain.
