Spin and orbital transport on ultrafast timescales (B13*)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2026
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 328545488

In this project, spin and orbital transport phenomena induced by THz and laser pulses will be studied theoretically. Employing the nonlinear Boltzmann equation and analyzing the time evolution of the one-particle density matrix, we aim to calculate nonequilibrium spin and orbital magnetization as well as spin and orbital currents in quasi-two-dimensional systems, including Rashba multilayers, transition metal dichalcogenide monolayers, and layered Kagome magnets. Our model-based approach enables us to analyze topology- and quantum geometry-related linear and nonlinear responses.
