Tuning topological electronic states and topological magnons (A01)
Subject Area
Experimental Condensed Matter Physics
Term
since 2023
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 492547816
Within this project we will identify the spectral signatures of the electronic band topology, such as nodal points, lines, planes, and flat bands, in the diagonal and off-diagonal optical conductivity of magnetic semi-metals, with the focus on kagome layer-based materials. The magnetically-driven band reconstruction and the tunability of the topological fermionic states will be studied by optical spectroscopy over a broad frequency range in external magnetic fields and under hydrostatic pressure, respectively. Furthermore, we will search for the signatures of bulk topological magnons and of topologically protected magnon edge states in honeycomb materials, pyrochlore compounds, and kagome magnets by magneto-optical THz spectroscopy.
