Quantum transport in the presence of engineered quantum fields (A03)

Subject Area Theoretical Condensed Matter Physics
Term since 2021
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 425217212
 
We theoretically investigate the interaction of engineered quantum fields with electronic and spintronic quantum transport. First, we address tunneling through sub-nanometer gaps initiated by ultrashort light pulses, causing a subcycle dynamics in the attosecond range due to the high nonlinearity. Second, we ask how the quantum information of a squeezed magnonic field is transformed into electronic current and how it can be detected via correlations. Both topics make heavy use of nonequilibrium field theoretical methods by using Keldysh path integrals.
