Fluctuations relation and external thermostats: an application to granular materials
F. Bonetto, G. Gallavotti, A. Giuliani +1
In this note we discuss a paradigmatic example of interacting particles subject to non conservative external forces and to the action of thermostats consisting of external (finite)…
