Effective Equations in complex systems: from Langevin to machine learning
Angelo Vulpiani, Marco Baldovin
The problem of effective equations is reviewed and discussed. Starting from the classical Langevin equation, we show how it can be generalized to Hamiltonian systems with non-stand…
Effective equations for reaction coordinates in polymer transport
Marco Baldovin, Fabio Cecconi, Angelo Vulpiani
In the framework of the problem of finding proper reaction coordinates (RCs) for complex systems and their effective evolution equations, we consider the case study of a polymer ch…
On the Fluctuation-Dissipation Relation in non-equilibrium and non-Hamiltonian systems
A. Sarracino, A. Vulpiani
We review generalized Fluctuation-Dissipation Relations which are valid under general conditions even in ``non-standard systems'', e.g. out of equilibrium and/or without a Hamilton…
Irreversibility and typicality: A simple analytical result for the Ehrenfest model
Marco Baldovin, Lorenzo Caprini, Angelo Vulpiani
With the aid of simple analytical computations for the Ehrenfest model, we clarify some basic features of macroscopic irreversibility. The stochastic character of the model allows…
Statistical mechanics of systems with long-range interactions and negative absolute temperature
Fabio Miceli, Marco Baldovin, Angelo Vulpiani
A Hamiltonian model living in a bounded phase space and with long-range interactions is studied. It is shown, by analytical computations, that there exists an energy interval in wh…
The Entropy Production of Ornstein-Uhlenbeck Active Particles: a path integral method for correlations
Lorenzo Caprini, Umberto Marini Bettolo Marconi, Andrea Puglisi +1
By employing a path integral formulation, we obtain the entropy production rate for a system of active Ornstein-Uhlenbeck particles (AOUP) both in the presence and in the absence o…
