Abstract
The noise characteristics of a single Anderson impurity coupled to two leads at different chemical potential is studied using the equation of motion method. We find that the current noise spectral density has an upturn as the frequency matches the chemical potential difference at low temperature. The low-frequency noise shows resonant behavior at equilibrium at low temperature because of the Kondo effect, and is suppressed significantly due to the Coulomb blockade effect on the impurity site when
