abstract = {We report the first measurement of the dynamical response of shot noise (measured at frequency ω) of a tunnel junction to an ac excitation at frequency ω0. The experiment is performed in the quantum regime, ω∼ ω0 kBT at very low temperature T = 35mK and high frequency ω0/2π = 6.2GHz. We observe that the noise responds in phase with the excitation, but not adiabatically. The results are in very good agreement with a prediction based on a new current-current correlator. 2008 The American Physical Society.},
