Fluctuation Formula in the Nose-Hoover thermostated Lorentz gas
arXiv:nlin/0401036 · doi:10.1103/PhysRevE.71.025202
Abstract
In this paper we examine numerically the Gallavotti-Cohen fluctuation formula for phase-space contraction rate and entropy production rate fluctuations in the Nosé-Hoover thermostated periodic Lorentz gas. Our results indicate that while the phase-space contraction rate fluctuations violate the fluctuation formula near equilibrium states, the entropy production rate fluctuations obey this formula near and far from equilibrium states as well.
