Nanostructures
Quantum coherence and correlation effects distinguish quantum transport through nanostructures from more conventional quasiclassical transport. A flexible and intensively studied model system are quantum dots where our work has focused on strongly coupled dots, the Coulomb blockade, and the Kondo effect. Most of our current effort focuses on molecular electronics where we investigate the influence of collective modes such as molecular vibrations or spin in single-molecule transistors.
