Persistent spin dynamics in magnetically ordered honeycomb cobalt oxides
Ping Miao, Xianghong Jin, Weiliang Yao +7
In the quest to find quantum spin liquids, layered cobalt oxides Na2Co2TeO6 and Na3Co2SbO6 have been proposed as promising candidates for approximating the Kitaev honeycomb model.…
Phonon thermal transport shaped by strong spin-phonon scattering in a Kitaev material NaCoTeO
Xiaochen Hong, Matthias Gillig, Weiliang Yao +7
The recent report of a half-quantized thermal Hall effect in the Kitaev material -RuCl has sparked a strong debate on whether it is generated by Majorana fermion edge curren…
Easy-plane multi- magnetic ground state of NaCoSbO
Yuchen Gu, Xintong Li, Yue Chen +9
NaCoSbO is a potential Kitaev magnet with a monoclinic layered crystal structure. Recent investigations of the -symmetric sister compound NaCoTeO have…
Phononic-magnetic dichotomy of the thermal Hall effect in the Kitaev-Heisenberg candidate material NaCoTeO
Matthias Gillig, Xiaochen Hong, Christoph Wellm +5
Majorana fermions as emergent excitations of the Kitaev quantum spin liquid ground state constitute a promising concept in fault tolerant quantum computation. Experimentally, the r…
Chern numbers of topological phonon band crossing determined with inelastic neutron scattering
Zhendong Jin, Biaoyan Hu, Yiran Liu +13
Topological invariants in the band structure, such as Chern numbers, are crucial for the classification of topological matters and dictate the occurrence of exotic properties, yet…
Magnetic molecular orbitals in MnSi
Zhendong Jin, Yangmu Li, Zhigang Hu +15
A large body of knowledge about magnetism is attained from models of interacting spins, which usually reside on magnetic ions. Proposals beyond the ionic picture are uncommon and s…

Xintong Li, Yuchen Gu, Yue Chen +12
We report magnetometry data obtained on twin-free single crystals of Na3Co2SbO6, which is considered a candidate material for realizing the Kitaev honeycomb model for quantum spin…
Excitations in the ordered and paramagnetic states of honeycomb magnet Na2Co2TeO6
Weiliang Yao, Kazuki Iida, Kazuya Kamazawa +1
Na2Co2TeO6 is a proposed approximate Kitaev magnet, yet its actual magnetic interactions are elusive due to a lack of knowledge on the full excitation spectrum. Here, using inelast…
Unusual heat transport of the Kitaev material NaCoTeO: putative quantum spin liquid and low-energy spin excitations
Xiaochen Hong, Matthias Gillig, Richard Hentrich +10
We studied the field dependent thermal conductivity () of NaCoTeO, a compound considered as the manifestation of the Kitaev model based on the high-spin Co$^{2…
Ferrimagnetism and anisotropic phase tunability by magnetic fields in NaCoTeO
Weiliang Yao, Yuan Li
NaCoTeO has recently been proposed to be a Kitaev-like honeycomb magnet. To assess how close it is to realizing Kitaev quantum spin liquids, we have measured magnetizat…
Topological spin excitations observed in a three-dimensional antiferromagnet
Weiliang Yao, Chenyuan Li, Lichen Wang +7
Band topology, or global wave-function structure that enforces novel properties in the bulk and on the surface of crystalline materials, is currently under intense investigations f…
