Dissipative single- and two-electron transfer via bridges — •Sabine Tornow1, F. Anders2, and R. Bulla11Theoretical Physics III,Center for Electronic Correlations and Magnetism,University of Augsburg — 2Institute of theoretical Physics,University of Bremen

Electron transfer (ET) reactions are common in chemical, physical and biological systems and are often performed via bridges. Dependent on the energy of the bridge and coupling to the environment the process can be an incoherent sequential ET or a coherent superexchange mediated ET. With the help of the time dependent Numerical Renormalization Group we investigate the coherent and incoherent dynamics in the nuclear tunnelling regime. Furthermore, we discuss the multi-electron dynamics when we include two excess electrons into the system at low as well as large temperatures.
