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…
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…
Magnetic ground state of the Kitaev NaCoTeO spin liquid candidate
Weiliang Yao, Yang Zhao, Yiming Qiu +4
As a candidate Kitaev material, NaCoTeO exhibits intriguing magnetism on a honeycomb lattice that is believed to be -symmetric. Here we report a neutron diffractio…
Methods pressure control apparatus for lithium metal battery
Bingyu Lu, Wurigumula Bao, Weiliang Yao +3
Lithium (Li) metal anodes are essential for developing next-generation high-energy-density batteries. However, Li dendrite/whisker formation caused short-circuiting issue and short…
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…
Bridging Nano and Micro-scale X-ray Tomography for Battery Research by Leveraging Artificial Intelligence
Jonathan Scharf, Mehdi Chouchane, Donal P. Finegan +11
X-ray Computed Tomography (X-ray CT) is a well-known non-destructive imaging technique where contrast originates from the materials' absorption coefficients. Novel battery characte…
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…
