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…
Heat transport of the kagomé Heisenberg quantum spin liquid candidate YCu(OH)Br: localized magnetic excitations and spin gap
Xiaochen Hong, Mahdi Behnami, Long Yuan +5
The spin-1/2 kagomé Heisenberg antiferromagnet is generally accepted as one of the most promising two-dimensional models to realize a quantum spin liquid state. Previous experiment…
Quantum Critical Magnetic Excitations in Spin-1/2 and Spin-1 Chain Systems
Y. Xu, L. S. Wang, Y. Y. Huang +9
The study of CoNbO sits at the confluence of simplicity and complexity: on one hand, the model for Ising chains -- the building blocks of CoNbO -- in a transverse f…
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…
High-field thermal transport properties of the Kitaev quantum magnet alpha-RuCl3: evidence for low-energy excitations beyond the critical field
Richard Hentrich, Xiaochen Hong, Matthias Gillig +11
We investigate the phononic in-plane longitudinal low-temperature thermal conductivity kappa_ab of the Kitaev quantum magnet alpha-RuCl3 for large in-plane magnetic fields up to 33…
Absence of magnetic thermal conductivity in the quantum spin liquid candidate YbMgGaO4
Y. Xu, J. Zhang, Y. S. Li +4
We present the ultra-low-temperature specific heat and thermal conductivity measurements on the single crystals of YbMgGaO, which was recently argued to be a promising candidat…
Quantum transport evidence for a three-dimensional Dirac semimetal phase in Cd3As2
L. P. He, X. C. Hong, J. K. Dong +4
The material termed three-dimensional (3D) Dirac semimetal has attracted great interests recently, since it is an electronic analogue to two-dimensional graphene. Starting from thi…
Specific heat and thermal conductivity of ferromagnetic magnons in Yttrium Iron Garnet
B. Y. Pan, T. Y. Guan, X. C. Hong +4
The specific heat and thermal conductivity of the insulating ferrimagnet YFeO (Yttrium Iron Garnet, YIG) single crystal were measured down to 50 mK. The ferromagneti…
Anderson localization of spinons in a spin-1/2 antiferromagnetic Heisenberg chain
B. Y. Pan, S. Y. Zhou, X. C. Hong +2
Anderson localization is a general phenomenon of wave physics, which stems from the interference between multiple scattering paths1,2. It was originally proposed for electrons in a…
Unveiling the quantum critical point of an Ising chain
Y. F. Dai, H. Zhang, S. Y. Zhou +7
Quantum phase transitions occur at zero temperature upon variation of some nonthermal control parameters. The Ising chain in a transverse field is probably the most-studied model u…
