Simulation of ultrafast processes and high harmonic generation in topological materials (A03)

• Subject Area: Theoretical Condensed Matter Physics
• Term: since 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 314695032

This project focuses on simulating and understanding topological materials and their excitations under ultrafast laser driving; it is motivated by experimental activities towards “lightwave spintronics” in Dirac systems. The main diagnostic observable will be the optical and magnetic responses in the high harmonic regime. Simulation tools will be developed based on the semiconductor Bloch equations with interactions included on mean-field level and beyond.
