Giant Phonon Anomalies in the Proximate Kitaev Quantum Spin Liquid -RuCl
H. Li, T. T. Zhang, A. Said +10
The Kitaev quantum spin liquid epitomizes an entangled topological state, for which two flavors of fractionalized low-energy excitations are predicted: the itinerant Majorana fermi…

Observation of a Chiral Wave Function in Twofold Degenerate Quadruple Weyl System BaPtGe
Haoxiang Li, Tiantian Zhang, A. Said +10
Topological states in quantum materials are defined by non-trivial topological invariants, such as the Chern number, which are properties of their bulk wave functions. A remarkable…
