The paper is devoted to a study of phase transitions in the Hermitian random matrix models with a polynomial potential. In an alternative equivalent language, we study families of equilibrium measures on the real line in a polynomial external field. The total mass of the measure is considered as the main parameter, which may be interpreted also either as temperature or time. Our main tools are differentiation formulas with respect to the parameters of the problem, and a representation of the…

Universality for multiplicative statistics of Hermitian random matrices and the integro-differential Painlev\'e II equation
We study multiplicative statistics for the eigenvalues of unitarily-invariant Hermitian random matrix models. We consider one-cut regular polynomial potentials and a large class of multiplicative

Quantum Mechanics in symmetry language
We consider symmetry as a foundational concept in quantum mechanics and rewrite quantum mechanics and measurement axioms in this description. We argue that issues related to measurements and physical

Asymptotics for the Partition Function in Two-Cut Random Matrix Models
AbstractWe obtain large N asymptotics for the random matrix partition function $$Z_N(V)=\int_{\mathbb{R}^N} \prod_{i <
Gravitational lensing by eigenvalue distributions of random matrix models
We propose to use eigenvalue densities of unitary random matrix ensembles as mass distributions in gravitational lensing. The corresponding lens equations reduce to algebraic equations in the complex
An equilibrium problem on the sphere with two equal charges
We study the equilibrium measure on the two dimensional sphere in the presence of an external field generated by two equal point charges. The support of the equilibrium measure is known as the

This paper considers the zero distribution of Hermite–Padé polynomials of the first kind associated with a vector function whose components are functions with a finite number of branch points in the


Generic behavior of the density of states in random matrix theory and equilibrium problems in the presence of real analytic external fields
The equilibrium measure in the presence of an external field plays a role in a number of areas in analysis, for example, in random matrix theory: The limiting mean density of eigenvalues is precisely
Phase transitions in multi-cut matrix models and matched solutions of Whitham hierarchies
We present a method for studying phase transitions in the large N limit of matrix models using matched solutions of Whitham hierarchies. The endpoints of the eigenvalue spectrum as functions of the
Breakdown of universality in multi-cut matrix models
We solve the puzzle of the disagreement between orthogonal polynomials methods and mean-field calculations for random N×N matrices with a disconnected eigenvalue support. We show that the difference

We describe the distribution of the first finite number of eigenvalues in a newly-forming band of the spectrum of the random Hermitian matrix model. The method is rigorously based on the

In this paper we use techniques from the theory of ODEs and also from inverse scattering theory to obtain a variety of results on the regularity and support properties of the equilibrium measure for
Asymptotics of the partition function for random matrices via Riemann-Hilbert techniques and applications to graphical enumeration
We study the partition function from random matrix theory using a well known connection to orthogonal polynomials, and a recently developed Riemann-Hilbert approach to the computation of detailed
Partition function for multi-cut matrix models
We consider the partition function Z N of a random matrix model with polynomial potential V(ξ) = t 1 ξ + t 2 ξ 2 + ··· + t 2d ξ 2d . It is known that the second logarithmic derivative of Z N with
Orthogonal polynomial ensembles in probability theory
We survey a number of models from physics, statistical mechanics, probability theory and combinatorics, which are each described in terms of an {it orthogonal polynomial ensemble}. The most prominent

In this paper, a new method is discussed to derive the eigenvalue density in a Hermitian matrix model with a general potential. The density is considered on one interval or multiple disjoint
