Vibration-induced thermoelectric effects in quantum dots — •Matti Laakso and Volker Meden — Institut für Theorie der Statistischen Physik, RWTH Aachen, Aachen, Germany

We study the thermoelectric transport through a quantum dot coupled to a single vibrational mode described by the Anderson-Holstein model. We use analytical methods in the linear response regime as well as the functional renormalization group (FRG) in the non-linear regime. We predict relatively large thermoelectric effects in the parameter regime where the phonon-mediated electron-electron interaction dominates over the bare Coulomb repulsion.
