GOE statistics for Lévy matrices

نویسندگان

چکیده

In this paper we establish eigenvector delocalization and bulk universality for Levy matrices, which are real, symmetric, $N \times N$ random matrices $\textbf{H}$ whose upper triangular entries independent, identically distributed $\alpha$-stable laws. First, if $\alpha \in (1, 2)$ $E \mathbb{R}$ is any energy bounded away from $0$, show that every of corresponding to an eigenvalue near $E$ completely delocalized the local spectral statistics around converge those Gaussian Orthogonal Ensemble (GOE) as $N$ tends $\infty$. Second, almost all (0, 2)$, there exists a constant $c(\alpha) > 0$ such same statements hold $|E| < c (\alpha)$.

Lévy Moving Averages and Spatial Statistics

in collaboration with Nicky Best and Katja Ickstadt 1 ' & $ % Moving Averages One common and flexible way of constructing stationary time series (discrete-time stochastic processes) is to begin with an i.i.d. X i ≡ j b j ζ i−j where j typically runs from 0 to some finite q ∈ N (or occasionally from 0 to ∞ or even from −∞ to ∞). It is straightforward to compute the mean and covariance of X i and...

Manifold Statistics for Essential Matrices

Riemannian geometry allows for the generalization of statistics designed for Euclidean vector spaces to Riemannian manifolds. It has recently gained popularity within computer vision as many relevant parameter spaces have such a Riemannian manifold structure. Approaches which exploit this have been shown to exhibit improved efficiency and accuracy. The Riemannian logarithmic and exponential map...

Critical statistics for non-Hermitian matrices.

We introduce a generalized ensemble of non-Hermitian matrices interpolating between the Gaussian Unitary Ensemble, the Ginibre ensemble, and the Poisson ensemble. The joint eigenvalue distribution of this model is obtained by means of an extension of the Itzykson-Zuber formula to general complex matrices. Its correlation functions are studied both in the case of weak non-Hermiticity and in the ...

Random Matrix Line Shape Theory with Applications to Lévy Statistics ∗

A model system of a bright state coupled to a manifold of dark states is analyzed with regard to the width distributions of the dark manifold induced in the bright state. Independent box shaped distributions are assumed for the energy distributions, the coupling distributions and the dark level width-distributions. The width distributions induced via the couplings from the dark levels into the ...

Spectral statistics of permutation matrices.

We compute the mean two-point spectral form factor and the spectral number variance for permutation matrices of large order. The two-point correlation function is expressed in terms of generalized divisor functions, which are frequently discussed in number theory. Using classical results from number theory and casting them in a convenient form, we derive expressions which include the leading an...
