Level statistics in the fractal phase of generalized Rosenzweig--Porter models
Victor Delapalme, Leticia F. Cugliandolo, Alexander K. Hartmann +2
The Rosenzweig--Porter (RP) random matrix ensemble has emerged as a minimal model for the integrability-to-chaos crossover in quantum many-body systems. Its phase diagram features…
Recoil of a driven tracer in a correlated medium
Marcin Piotr Pruszczyk, Davide Venturelli, Andrea Gambassi
We study the stochastic dynamics of a Brownian particle after it is suddenly released from a harmonic trap moving with constant velocity through a fluctuating correlated medium, de…
Structure and dynamics of a Rouse polymer in a fluctuating correlated medium
Pietro Luigi Muzzeddu, Davide Venturelli, Andrea Gambassi
We study the static and dynamical properties of a harmonically confined Rouse polymer coupled to a fluctuating correlated medium, which affect each other reciprocally during their…
The XY model with vision cone: non-reciprocal vs. reciprocal interactions
Gabriele Bandini, Davide Venturelli, Sarah A. M. Loos +2
We study the behavior of the classical XY model on a two-dimensional square lattice, with interactions occurring within a vision cone of each spin. Via Monte Carlo simulations, we…
