Coherent optical spin and charge control in nanostructures (B06)

• Subject Area: Theoretical Condensed Matter Physics
• Term: from 2009 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 32152442

We theoretically investigate the quantum coherent optical control of spin and charge degrees of freedom of single or few quantum objects in nanosystems. The nanosystems under study are quantum dots, defect centers with spin in diamond and silicon carbide, and semiconductor or metal nanogaps. The main goals of the project are the theoretical description of ultrafast photon-induced electric transport through nanogaps, the understanding of ultrafast optical control of charge and spin degrees of freedom of localized electrons in nanostructures, the controlled optical generation of spin- and valley-polarized carriers in nanostructures based of two-dimensional materials, optical preparation and detection of nuclear spin states in semiconductor nanostructures, and steps towards long-distance entanglement between spins.
