Asymptotic long-range order for the XY-model on random geometric graphs

Margherita Disertori, Max Mihailescu

We study the classical $X Y$ -model on random geometric graphs $G_{n, ε}$ , which are obtained by sampling $n \in N$ independent points in a finite domain…

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 $H^{2∣2 n}$ nonlinear sigma models

Margherita Disertori, Javier Durán Fernández, Luca Fresta

We consider a family of nonlinear sigma models on $Z^{d}$ whose target space is the hyperbolic super manifold $H^{2∣2 n}$ , $n > 1$ , introduced by Crawford as an extension of…
