In this project, we will study the interplay between quantum charge fluctuations and electromagnetic fields. The goal is to elucidate both theoretically and experimentally the role of charge fluctuations in the electronic transport through metallic and superconducting single-electron transistors far away from equilibrium. Experimentally, the nonequilibrium will be induced by microwave irradiation and probed by DC transport measurements at very low temperatures. The theoretical study is performed using a Keldysh real-time Green’s function approach.
