Magnetic resonance spectroscopy on quantum spin liquids and Weyl semimetals (B04)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 492547816

Electron spin resonance and nuclear magnetic resonance serve as site selective probes of the dynamic susceptibility in constrained quantum matter. In triangular and Kitaev magnets these techniques are applied in search for signatures of fractionalized excitations and entanglement characteristic of quantum-spin liquids. In magnetic topological semimetals anomalies in the electronic density of states at the Fermi level and their variation with magnetic field can be resolved, complementing spectroscopic studies in other projects in revealing information about band topology.
