Query: Coherent transport in disordered metals out of equilibrium   We derive a formula for the quantum corrections to the electrical current for
a metal out of equilibrium. In the limit of linear current-voltage
characteristics our formula reproduces the well known Altshuler-Aronov
correction to the conductivity of a disordered metal. The current formula is
obtained by a direct diagrammatic approach, and is shown to agree with what is
obtained within the Keldysh formulation of the non-linear sigma model. As an
application we calculate the current of a mesoscopic wire. We find a
current-voltage characteristics that scales with $eV/kT$, and calculate the
different scaling curves for a wire in the hot-electron regime and in the
regime of full non-equilibrium.
