When do nonequilibrium forms of disordered energy qualify as heat? We address this
question in the context of cyclically operating heat engines feeding on nonequilibrium …

Abstract Since Albert Einstein's seminal 1905‐paper on Brownian motion, the temperature of
fluids and gases of known viscosity can be deduced from observations of the fluctuations of …

Il moto Browniano caldo (hot Brownian motion) indica la dinamica stocastica di una
particella colloidale più calda del fluido in cui è immersa. Questa condizione si realizza …

This thesis collects the published papers of ours on the subject of classical nonequilibrium
statistical mechanics. Mainly stochastic systems are considered, with special regard to …
