Current fluctuations in non-equilibrium systems

Bernard Derrida, Ecole Normale Superieure

This talk will review a series of results obtained
recently on the fluctuations of current in diffusive systems for
several geometries:

steady state obtained by contact with two reservoirs or two heat baths, system at equilibrium on a ring geometry, two systems at unequal temperatures which are connected at time t=0.

Some open questions will also be discussed, in particular the behavior of one dimensional mechanical systems and its similarity with diffusive systems at a phase transition..
