Adiabatic Pumping through interacting Quantum Dots — •Janine Splettstoesser^1,2, Michele Governale¹, Rosario Fazio¹, and Jürgen König² — ¹Scuola Normale Superiore, Pisa — ²Ruhr-Universität Bochum

There has been much recent experimental and theoretical interest in adiabatic quantum pumping through mesoscopic electronic devices such as quantum dots. A systematic framework exists to analyze such a system in the non-interacting limit starting from the so-called Brouwer’s formula. In interacting systems a general formalism to describe adiabatic pumping is not available until now. Using the nonequilibrium-Green-function approach for transport through interacting systems (by Jauho, Wingreen and Meir), we write a formula to calculate adiabatic pumping through an interacting quantum dot.
