Gradual eigenvector ergodization in coupled Ginibre matrices
Margherita Disertori, Yan V. Fyodorov
Non-Hermitian random matrices provide a useful framework for understanding universal characteristics of dissipative quantum chaotic systems with loss or gain. We consider a model o…
Exponential decay of correlations at high temperature in nonlinear sigma models
Margherita Disertori, Javier Durán Fernández, Luca Fresta
We consider a family of nonlinear sigma models on whose target space is the hyperbolic super manifold , , introduced by Crawford as an extension of…
Phase transition in the Integrated Density of States of the Anderson model arising from a supersymmetric sigma model
Margherita Disertori, Valentin Rapenne, Constanza Rojas-Molina +1
We study the Integrated Density of States (IDS) of the random Schrödinger operator appearing in the study of certain reinforced random processes in connection with a supersymmetri…
Restrictions of some reinforced processes to subgraphs
Margherita Disertori, Franz Merkl, Silke W. W. Rolles
We prove that the restriction of the vertex-reinforced jump process to a subset of the vertex set is a mixture of vertex-reinforced jump processes. A similar statement holds for th…
