Titre: Non-equilibrium steady states in the partition free approach

Abstract: "Assume that we have a system composed of a number of leads
and a small sample, at termal equilibrium. At t=0 we switch on a bias
between the leads, which might depend on time for a finite time
interval. We prove that the system attains a non-equilibrium steady
state and compute the stationary charge current. Note that we do not
restrict ourselves to linear response theory. We will also discuss the
complementarity of our approach with the one of Jaksic-Pillet-Ruelle."
