Ultrafast control of spins coupled to excitons, phonons, and valleys in 2D materials (B08)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 328545488

The project will explore the ultrafast control of spin and other degrees of freedom coupled to it in 2D materials using time-dependent electric fields and mechanical strain as ultrafast “control knobs”. In 2D magnet CrSBr, the project studies the coupling between optical and acoustic magnons, the AC Stark effect, and magnon hybridization phenomena. In 2D semiconductors from the group of transition metal dichalcogenides, the project studies the coupling between the spin and valley pseudospin degrees of freedom, the relaxation of the valley degree of freedom and the dynamics and transport of orbital magnetization.
