Quantum many-body effects in transport through quantum dots: renormalization-group approaches

Full text: The understanding of correlation effects and their impact on the quantum coherence is of fundamental importance in view of technological implementations of quantum computing schemes and nanoelectronic applications. Using recently developed renormalization-group approaches, we investigate the effect of Coulomb interactions and their characteristic signatures in the electronic transport through quantum dots. We provide examples for the rich many-body physics of simple model systems in and out of equilibrium, as well as challenging extensions to more complex systems as realized in experiments. (author)
