摘要
A d.c. current can be pumped through a quantum dot by periodically varying two independent parameters and , like a gate voltage or magnetic field. We present a formula that relates the pumped current to the parametric derivatives of the scattering matrix of the system. As an application we compute the statistical distribution of the pumped current in the case of a chaotic quantum dot.
