The physics of mesoscopic quantum systems, i.e., electronic structures in the nanometer range, is one of the most active research areas of condensed-matter physics. These systems allow us to study fundamental physics questions, and their understanding is necessary for possible future electronic device applications. The goal of our research is to exploit and analyze quantum effects in such circuits, e.g. novel excitations like Majorana quasiparticles. These particles have been predicted but not yet been found in particle physics. Another interesting field that we work on is generalized quantum measurements and quantum model systems that can be used to test the foundations and limits of quantum mechanics. In particular, our group (about 3 PhD students and 3 Postdocs) plans to study the interplay of electric currents through nanostructures with mechanical degrees of freedom (nanomechanics). We are also interested in fluctuation and noise phenomena: electrical currents are not exactly constant but fluctuate, and these fluctuations contain a great deal of information about the quantum nature of the electrons that carry the current. We will also investigate ultracold atoms which can be used to study quantum coherence and quantum many-body phenomena. Finally, we study macroscopic quantum phenomena like superconductivity.
