Abstract
A dc current can be pumped through a quantum dot by periodically varyi ng two independent parameters X-1 and X-2, like a gate voltage or magn etic field. We present a formula that relates the pumped current to th e parametric derivatives of the scattering matrix S(X-1,X-2) of the sy stem. As an application we compute the statistical distribution of the pumped current in the case of a chaotic quantum dot. [S0163-1829(98)5 2240-0].
