Abstract

We study current correlation functions in a diffusive junction out of equilibrium. We calculate corrections to the electric current and to the zero-frequency shot noise due to electron-electron interactions. Contrary to the equilibrium situation (where the corrections to the current and to the current noise are related through the fluctuation-dissipation theorem), these two quantities behave differently: the corrections to the electron current are governed by the largest of temperature and applied voltage, while the correction to the shot noise is always governed by the temperature.
