Giant phonon anomalies in the proximate Kitaev quantum spin liquid α-RuCl3
Giant phonon anomalies in the proximate Kitaev quantum spin liquid α-RuCl3
The Kitaev quantum spin liquid epitomizes an entangled topological state, for which two flavors of fractionalized low-energy excitations are predicted: the itinerant Majorana fermion and the Z2 gauge flux. It was proposed recently that fingerprints of fractional excitations are encoded in the phonon spectra of Kitaev quantum spin liquids through …
