We analyze a systematic algorithm for the exact computation of the current cumulants in stochastic nonequilibrium systems, recently discussed in the framework of full counting statistics for mesoscopic systems. This method is based on identifying the current cumulants from a Rayleigh-Schrödinger perturbation expansion for the generating function. Here it is derived from a simple path-distribution identity and extended to the joint statistics of multiple currents. For a possible thermodynamical… Expand

Analysis of slow transitions between nonequilibrium steady states
Transitions between nonequilibrium steady states obey a generalized Clausius inequality, which becomes an equality in the quasistatic limit. For slow but finite transitions, we show that the behaviorExpand

Universal cumulants of the current in diffusive systems on a ring.
This work calculates exactly the first cumulants of the integrated current and of the activity of the symmetric simple exclusion process on a ring with periodic boundary conditions and indicates that for large system sizes the large deviation functions of the current and the activity take a universal scaling form.
