| Research Abstract |
In this project, we have clarified theoretically several properties of zero-bias currents induced by a quantum pumping mechanism by utilizing a novel transfer matrix approach developed by us. In particular, we found that non-adiabatic quantum pumping in a rather simple system can realizes large magnitudes of charge currents or pure spin currents without accompanying any charge currents.
