Abstract
We consider adiabatic pumping of electrons through a quantum dot. There are two ways to operate the pump: to create a dc current or to create a dc voltage We demonstrate that, for very slow pumping, and are not simply related via the dc conductance G as For the case of a chaotic quantum dot, we consider the statistical distribution of Results are presented for the limiting cases of a dot with single-channel and with multichannel point contacts.
