Theshot noise in the current through a quantum dot iscalculated as a function of voltage from the high-voltage Coulomb-blockadedregime to the low-voltage Kondo regime. Using several complementary approaches,it is shown that the zero-frequency shot noise (scaled bythe voltage) exhibits a nonmonotonic dependence on voltage, with apeak around the Kondo temperature. Beyond giving a good estimateof the Kondo temperature, it is shown that the shotnoise yields additional information on the effects of electronic correlationson the local density of states in the Kondo regime,unaccessible in traditional transport measurements. ©2002 The American Physical Society

    Here energy-independent couplings are assumed.
  17. These expressions assume that that the change in chemical potential due to the voltage drop takes place in one lead. If the voltage drops symmetrically over the two leads, then the integral runs from –V/2 to V/2.
