Pico - Quantum Phenomena and Devices

We investigate mesoscopic physics and its sensor applications. The main focus is on charge transport and thermal properties of metallic, superconducting and hybrid nanostructures. Particular research topics include electronic thermometry and refrigeration, nonequilibrium effects, Josephson devices, quantized and coherent charge pumping, noise, fluctuations and full counting statistics of charge and heat transport.
