Multiple electron transfer and transport through a DNA dimer — •Sabine Tornow1, Gertrud Zwicknagl1, Ralf Bulla2, and Frithjof Anders3 — 1Inst. math. Physik, TU Braunschweig — 2Inst. th. Physik, U Köln — 3Inst. th. Physik, U Dortmund
We investigate multiple electron transfer in a donor-bridge-acceptor system where the molecular bridge comprises a DNA dimer (AT-AT or GC-GC) strongly coupled to a bosonic bath. The time dependent population probabilities and transfer characteristics of multiple electrons is calculated with the time-dependent renormalization group method at low temperatures and kinetic equations at large temperatures. The related transport properties for a system where donor and acceptor are replaced by left and right leads is discussed in different temperature and coupling regimes.
