Journal ArticleDOI
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.
Journal ArticleDOI
Strong interplay between stripe spin fluctuations, nematicity and superconductivity in FeSe
Qisi Wang,Yao Shen,Bingying Pan,Yiqing Hao,Mingwei Ma,Fang Zhou,P. Steffens,Karin Schmalzl,Thomas Forrest,Mahmoud Abdel-Hafiez,Xiao-Jia Chen,Dmitriy A. Chareev,Alexander N. Vasiliev,Alexander N. Vasiliev,Alexander N. Vasiliev,P. Bourges,Yvan Sidis,Huibo Cao,Jun Zhao +18 more
TL;DR: The results support recent theoretical proposals that both nematicity and superconductivity are driven by spin fluctuations.
Journal ArticleDOI
Spinon Fermi surface in a triangular lattice quantum spin liquid YbMgGaO4
Yao Shen,Yaodong Li,Hongliang Wo,Yuesheng Li,Shoudong Shen,Bingying Pan,Qisi Wang,Helen Walker,P. Steffens,Martin Boehm,Yiqing Hao,D. L. Quintero-Castro,Leland Weldon Harriger,Lijie Hao,Siqin Meng,Qingming Zhang,Gang Chen,Jun Zhao +17 more
TL;DR: In this article, the authors reported neutron scattering measurements that reveal broad spin excitations covering a wide region of the Brillouin zone in an extremely clean antiferromagnet YbMgGaO4.
Journal ArticleDOI
Magnetic ground state of FeSe.
Qisi Wang,Yao Shen,Bingying Pan,Xiaowen Zhang,K. Ikeuchi,Kazuki Iida,Andrew D. Christianson,Helen Walker,D. T. Adroja,Mahmoud Abdel-Hafiez,Xiao-Jia Chen,Dmitriy A. Chareev,Alexander N. Vasiliev,Jun Zhao +13 more
TL;DR: Inelastic neutron-scattering experiments that reveal both stripe and Néel spin fluctuations over a wide energy range at 110 K suggest that FeSe is a novel S=1 nematic quantum-disordered paramagnet interpolating between the NÉel and stripe magnetic instabilities.
