Dynamics of stochastic oscillator chains with harmonic and FPUT potentials
Emilio N. M. Cirillo, Matteo Colangeli, Claudio Giberti +1
Inspired by recent studies on deterministic oscillator models, we introduce a stochastic one-dimensional model for a chain of interacting particles. The model consists of oscil…

Dynamics of the Kac Ring Model with switching scatterers
Leonid A. Bunimovich, Emilio N. M. Cirillo, Matteo Colangeli +1
We introduce a generalized version of the Kac ring model in which particles are of two types, black and white. Black particles modify the environment through which all particles mo…

Dissipation functions and Brownian oscillators
Matteo Colangeli, Lamberto Rondoni, Pasquale Vozza
We develop a general framework for response theory in diffusion processes governed by Fokker-Planck equations, based on the notion of the Dissipation Function. Using the analytical…
