The proposed research concerns non-equilibrium transport properties of nanosystems such as quantum dots and quantum wires. This is a timely topic, where fundamental issues of physics are at stake, and numerous technological applications possible.
This project is particularly interested in the influence on transport properties of the interactions, of the coupling to the environment, and of strong quantum effects. One of the specific aims is to find new ways to detect charge fractionalization, spin charge separation, and fractional statistics in one-dimensional systems.
Another aim is to deepen our understanding of current experimental setups, by taking into account features not accounted for in previous research due to the lack of proper mathematical tools. The applicant's expertise in perturbative approaches (in particular the Keldysh formalism) will be combined with the host's expertise in non-preservative methods of quantum field theory to make progress on some key questions.
Among those are: the possibility of detecting charge fractionalization in multiple current correlators, the possibility of observing physical consequences of fractional statistics, the properties of third and higher cumulants of the noise, the role of superconducting leads (as opposed to metallic leads).
