Topological phases in heavy-fermion insulators and semimetals, and the importance of time-reversal or inversion symmetry (C06)

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2015 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 258499086

We aim at the physical realization of rare-earth based topological materials and their systematic investigation by different spectroscopic methods. The starting point are mainly ternary compounds containing cerium or thulium. In addition to using bulk samples, a particular emphasis will be on the in situ MBE growth, which allows a more flexible preparation in a larger phase space area. The samples will be investigated by angle resolved photoemission spectroscopy (ARPES, SR-ARPES) and X-ray methods (XAS, XMC/LD, resonant reflectivity), yielding fundamental information about the relevant microscopic physical parameters and their complex interplay.
