[Distributions du travail et de la chaleur dans des systèmes hors équilibre]
Nous passons en revue et discutons les équations régissant la distribution du travail effectué sur un système manipulé hors d'équilibre, ainsi que celles qui régissent le flux d'entropie vers un réservoir dans un système hors d'équilibre. Nous exploitons ces équations dans l'étude de la transition de phase dans les chemins d'un modèle d'Ising champ moyen manipulé et de la fonction des grandes déviations pour le flux d'entropie dans le modèle d'exclusion asymétrique à probabilités de transition périodiques dans le temps.
We review and discuss the equations governing the distribution of work done on a system which is driven out of equilibrium by external manipulation, as well as those governing the entropy flow to a reservoir in a nonequilibrium system. We take advantage of these equations to investigate the path phase transition in a manipulated mean-field Ising model and the large-deviation function for the heat flow in the asymmetric exclusion process with periodically varying transition probabilities.
