Probing exciton structure and dynamics in two-dimensional magnets and spintronic heterostructures (B11#)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 328545488

The exciton is a central quasiparticle in transition metal dichalcogenides (TMDCs) and in 2D semiconductor magnets of interest to the TRR. In project B11, we employ polarization-resolved broadband coherent two-dimensional electronic spectroscopy (2DES) to probe how excitons interact with spins, phonons and electronic excitations in 2D magnets and heterostructures. We aim for an improved fundamental understanding of how magnetic order influences excitonic properties, and vice versa, i.e. the role that excitons play in ultrafast magnetization.
