Static and dynamic control of excitations in topological quantum matter (B07)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277146847

Using microwave techniques in the GHz range for spectroscopy or transport experiments, this project addresses the dynamics and control of magnetic or electronic excitations in topological quantum materials. The subjects reach from edge plasmons in the quantum anomalous Hall effect considering the possible influence of charge puddles in bulk and surface, include phase transitions in planar Josephson junctions and the control of embedded magnetic domain walls, as well as the stimulation of magnetic modes in skyrmion crystals and chiral magnets in terms of driven phases in active matter.
