Excess and loss of entropy production for different levels of coarse-graining
Pierpaolo Bilotto, Lorenzo Caprini, Angelo Vulpiani
We investigate the effect of coarse-graining on the energetics properties of a system, focusing on entropy production. As a case of study, we consider a one-dimensional colloidal p…
Statistical Features of High-Dimensional Hamiltonian Systems
Marco Baldovin, Giacomo Gradenigo, Angelo Vulpiani
In this short review we propose a critical assessment of the role of chaos for the thermalization of Hamiltonian systems with high dimensionality. We discuss this problem for both…
A handy fluctuation-dissipation relation to approach generic noisy systems and chaotic dynamics
Marco Baldovin, Lorenzo Caprini, Angelo Vulpiani
We introduce a general formulation of the fluctuation-dissipation relations (FDR) holding also in far-from-equilibrium stochastic dynamics. A great advantage of this version of the…
Response and flux of information in extended non-equilibrium dynamics
Camilla Sarra, Marco Baldovin, Angelo Vulpiani
It is well known that entropy production is a proxy to the detection of non-equilibrium, i.e. of the absence of detailed balance; however, due to the global character of this quant…
Statistical Mechanics of Systems with Negative Temperature
Marco Baldovin, Stefano Iubini, Roberto Livi +1
Do negative absolute temperatures matter physics and specifically Statistical Physics? We provide evidence that we can certainly answer positively to this vexata quaestio. The grea…
