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…
Super-poissonian noise, negative differential conductance, and relaxation effects in transport through molecules, quantum dots and nanotubes
A. Thielmann, M. H. Hettler, J. König +1
We consider charge transport through a nanoscopic object, e.g. single molecules, short nanotubes, or quantum dots, that is weakly coupled to metallic electrodes. We account for sev…
Shot noise in tunneling transport through molecules and quantum dots
Axel Thielmann, Matthias H. Hettler, Jürgen König +1
We consider electrical transport through single molecules coupled to metal electrodes via tunneling barriers. Approximating the molecule by the Anderson impurity model as the simpl…
