Evidence for a spinon Fermi surface in a triangular-lattice quantum-spin-liquid candidate
Yao Shen,Yaodong Li,Hongliang Wo,Yuesheng Li,Shoudong Shen,Bingying Pan,Qisi Wang,Helen Walker,Paul Steffens,Martin Boehm,Yiqing Hao,D. L. Quintero-Castro,Leland Harriger,Matthias Frontzek,Lijie Hao,Siqin Meng,Qingming Zhang,Qingming Zhang,Gang Chen,Jun Zhao +19 more
TL;DR: Theoretical studies have proposed various quantum spin liquid ground states, most of which are characterized by exotic spin excitations with fractional quantum numbers (termed "spinons") as discussed by the authors.
