Exploring out-of-equilibrium systems — •Luca Peliti — Dipartimento di Scienze Fisiche and Unita’ CNR-INFM, Universita’ No-dqFederico IINo-dq, I-80126 Napoli (Italy)

I describe a new approach for the simulation of systems in a steady state out of equilibrium. The approach is inspired by the Diffusion Monte Carlo technique for the solution of the Schroedinger equation, and allows for the evaluation of the large deviation functional as a function of (spatially local or global) observables which are local in time. The method is illustrated with the current fluctuations of the Totally Asymmetric Exclusion Process and with the entropy production distribution of a driven Lorentz gas.
