The Spinon Fermi Surface U(1) Spin Liquid in a Spin-Orbit-Coupled Triangular Lattice Mott Insulator YbMgGaO4
Yao Dong Li, Yuan-Ming Lu, Gang Chen
Motivated by the recent progress on the spin-orbit-coupled triangular lattice spin liquid candidate YbMgGaO4, we carry out a systematic projective symmetry group analysis and mean-…
The effect of spin-orbit coupling on the effective-spin correlation in YbMgGaO4
Yao-Dong Li, Yao Shen, Yuesheng Li +2
Motivated by the recent experiments on the triangular lattice spin liquid YbMgGaO, we explore the effect of spin-orbit coupling on the effective-spin correlation of the Yb loca…
Hidden multipolar orders of dipole-octupole doublets on a triangular lattice
Yao-Dong Li, Xiaoqun Wang, Gang Chen
Motivated by the recent development in strong spin-orbit-coupled materials, we consider the dipole-octupole doublets on the triangular lattice. We propose the most general interact…
Kitaev materials beyond iridates: order by quantum disorder and Weyl magnons in rare-earth double perovskites
Fei-Ye Li, Yao-Dong Li, Yue Yu +2
Motivated by the experiments on the rare-earth double perovskites, we propose a generalized Kitaev-Heisenberg model to describe the generic interaction between the spin-orbit-entan…
Evidence for a spinon Fermi surface in a triangular lattice quantum spin liquid candidate
Yao Shen, Yao-Dong Li, Hongliang Wo +16
A quantum spin liquid is an exotic quantum state of matter in which spins are highly entangled and remain disordered down to zero temperature. Such a state of matter is potentially…
Symmetry Enriched U(1) Topological Orders for Dipole-Octupole Doublets on a Pyrochlore Lattice
Yao Dong Li, Gang Chen
Symmetry plays a fundamental role in our understanding of both conventional symmetry breaking phases and the more exotic quantum and topological phases of matter. We explore the ex…
Weyl magnons in breathing pyrochlore antiferromagnets
Fei-Ye Li, Yao-Dong Li, Yong Baek Kim +3
Frustrated quantum magnets not only provide exotic ground states and unusual magnetic structures, but also support unconventional excitations in many cases. Using a physically rele…
