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

energy-independent couplings are assumed.

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.
