dc.descriptionWe analyze the effect of Coulomb interaction on the noise of electric current through an open quantum dot. We demonstrate that the ensemble average value of the noise power acquires an interaction correction even for a dot coupled to the leads by reflectionless point contacts, when the ensemble average conductance is known to have no interaction corrections. To leading order, the correction to the noise originates from the formation of a nonequilibrium state of the Coulomb field describing the interaction between electrons. We find the dependence of the current noise power on the electron temperature, the applied voltage bias, and the strength of the Coulomb interaction.
