Abstract We start with a rather detailed, general discussion of recent results of the replica approach to statistical mechanics of a single classical particle placed in a random N(≫1)-dimensional Gaussian landscape and confined by a spherically symmetric potential suitably growing at infinity. Then we employ random matrix methods to calculate the density of stationary points, as well as minima, of the associated energy surface. This is used to show that for a generic smooth, concave confining… 

Statistical mechanics of a single particle in a multiscale random potential: Parisi landscapes in finite-dimensional Euclidean spaces

We construct an N-dimensional Gaussian landscape with multiscale, translation invariant, logarithmic correlations and investigate the statistical mechanics of a single particle in this environment.

High-Dimensional Random Fields and Random Matrix Theory

The important role of the GOE "edge scaling" spectral region and the Tracy-Widom distribution of the maximal eigenvalue of GOE matrices for providing an accurate quantitative description of the universal features of the topology trivialization scenario are revealed.

Superposition of random plane waves in high spatial dimensions: Random matrix approach to landscape complexity

Motivated by current interest in understanding statistical properties of random landscapes in high-dimensional spaces, we consider a model of the landscape in [Formula: see text] obtained by

Landscape cosmology posits the existence of a convoluted, multidimensional, scalar potential—the “landscape”—with vast numbers of metastable minima. Random matrices and random functions in many

We obtain explicit expressions for the annealed complexities associated, respectively, with the total number of (i) stationary points and (ii) local minima of the energy landscape for an elastic

Statistical Distribution of Quantum Entanglement for a Random Bipartite State

We compute analytically the statistics of the Renyi and von Neumann entropies (standard measures of entanglement), for a random pure state in a large bipartite quantum system. The full probability

Random Matrices and Complexity of Spin Glasses

This study enables detailed information about the bottom of the energy landscape, including the absolute minimum, and the other local minima, and describes an interesting layered structure of the low critical values for the Hamiltonians of these models.

Hessian eigenvalue distribution in a random Gaussian landscape

A bstractThe energy landscape of multiverse cosmology is often modeled by a multi-dimensional random Gaussian potential. The physical predictions of such models crucially depend on the eigenvalue

We consider the number and distribution of minima in random landscapes defined on non-Euclidean lattices. Using an ensemble where random landscapes are reweighted by a fugacity factor z for each



Density of stationary points in a high dimensional random energy landscape and the onset of glassy behavior

The density of stationary points and minima of a N ≫ 1 dimensional Gaussian energy landscape has been calculated. It is used to show that the point of zero-temperature replica symmetry breaking in

Complexity of random energy landscapes, glass transition, and absolute value of the spectral determinant of random matrices.

Finding the mean of the total number N(tot) of stationary points for N-dimensional random energy landscapes is reduced to averaging the absolute value of the characteristic polynomial of the

Abstract: By using a simple interpolation argument, in previous work we have proven the existence of the thermodynamic limit, for mean field disordered models, including the Sherrington-Kirkpatrick

Glass transition of a particle in a random potential, front selection in nonlinear renormalization group, and entropic phenomena in Liouville and sinh-Gordon models.

Applications to Dirac fermions in random magnetic fields at criticality reveal a peculiar "quasilocalized" regime (corresponding to the glass phase for the particle), where eigenfunctions are concentrated over a finite number of distant regions, and allow us to recover the multifractal spectrum in the delocalized regime.

The existence of two asymptotic time regimes: stationary dynamics, slow aging dynamics with violation of equilibrium theorems are demonstrated and an analytical solution of these equations is obtained.

Large deviations of extreme eigenvalues of random matrices.

The average density of states in matrices whose eigenvalues are restricted to be larger than a fixed number zeta is calculated, thus generalizing the celebrated Wigner semicircle law.

Free-energy landscapes, dynamics, and the edge of chaos in mean-field models of spin glasses

Metastable states in Ising spin-glass models are studied by finding iterative solutions of mean-field equations for the local magnetizations. Two different equations are studied: the TAP equations
