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…
Hybrid Weyl Semimetal
Fei-Ye Li, Xi Luo, Xi Dai +3
We construct a tight-binding model realizing one pair of Weyl nodes and three distinct Weyl semimetals. In the type-I (type-II) Weyl semimetal, both nodes belong to type-I (type-II…
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…
