Non-equilibrium polaron hopping transport through DNA
Benjamin B. Schmidt, Matthias H. Hettler, Gerd Schön
We study the electronic transport through short DNA chains with various sequences of base pairs between voltage-biased leads. The strong coupling of the charge carriers to local vi…
Cross-correlations in transport through parallel quantum dots
Sebastian Haupt, Jasmin Aghassi, Matthias H. Hettler +1
We investigate cross-correlations in the tunneling currents through two parallel quantum dots coupled to independent electrodes and gates and interacting via an inter-dot Coulomb i…
Co-tunneling assisted sequential tunneling in multi-level quantum dots
Jasmin Aghassi, Matthias H. Hettler, Gerd Schön
We investigate the conductance and zero-frequency shot noise of interacting, multi-level quantum dots coupled to leads. We observe that co-tunneling assisted sequential tunneling (…
Shot noise in transport through "double quantum dots"
Jasmin Aghassi, Axel Thielmann, Matthias H. Hettler +1
Motivated by activities of several experimental groups we investigate electron transport through two coherent, strongly coupled quantum dots ("double quantum dots"), taking into ac…
Strongly enhanced shot noise in chains of quantum dots
J. Aghassi, A. Thielmann, M. H. Hettler +1
We study charge transport through a chain of quantum dots. The dots are fully coherent among each other and weakly coupled to metallic electrodes via the dots at the interface, thu…
Co-tunneling current and shot noise in quantum dots
A. Thielmann, M. H. Hettler, J. König +1
We derive general expressions for the current and shot noise, taking into account non-Markovian memory effects. In generalization of previous approaches our theory is valid for arb…
