Featureless quantum paramagnet with frustrated criticality and competing spiral magnetism on spin-1 honeycomb lattice magnet
Jian Qiao Liu, Fei Ye Li, Gang Chen +1
We study the spin-1 honeycomb lattice magnets with frustrated exchange interactions. The proposed microscopic spin model contains first and second neighbor Heisenberg interactions…
Asymmetric Ferromagnetic Criticality in Pyrochlore Ferromagnet LuVO
N. Su, F. -Y. Li, Y. Y. Jiao +7
Critical phenomenon at the phase transition reveals the universal and long-distance properties of the criticality. We study the ferromagnetic criticality of the pyrochlore magnet L…
Upper branch magnetism in quantum magnets: Collapses of excited levels and emergent selection rules
Changle Liu, Fei Ye Li, Gang Chen
In many quantum magnets especially the rare-earth ones, the low-lying crystal field states are not well separated from the excited ones and thus are insufficient to describe the lo…
Emergent quantum criticality from spin-orbital entanglement in Mott insulators: the case of a diamond lattice antiferromagnet
Fei-Ye Li, Gang Chen
Motivated by the recent activities on the Ni-based diamond lattice antiferromagnet NiRhO, we theoretically explore on a general ground the unique spin and orbital physics f…
Competing phases and topological excitations of spin-one pyrochlore antiferromagnets
Fei Ye Li, Gang Chen
Most works on pyrochlore magnets deal with the interacting spin-1/2 local moments. We here study the spin-one local moments on the pyrochlore lattice, and propose a generic interac…
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…
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…
