Field-induced phase transitions and quantum criticality in a honeycomb antiferromagnet Na3Co2SbO6
Ze Hu, Yue Chen, Yi Cui +10
We performed 23Na NMR measurements on a single-domain crystal of the Kitaev material Na3Co2SbO6, with magnetic field applied along the crystalline a axis. A positive Curie-Weiss co…
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.…
Anomalous transverse optic phonons in SnTe and PbTe -- revisited
Zehua Li, Shasha Li, John-Paul Castellan +5
We present a study of the soft transverse optic phonon mode in SnTe in comparison to the corresponding mode in PbTe using inelastic neutron scattering and ab-initio lattice dynamic…
Dynamical structural instability and its implication on the physical properties of infinite-layer nickelates
Chengliang Xia, Jiaxuan Wu, Yue Chen +1
We use first-principles calculations to find that in infinite-layer nickelates NiO, the widely studied tetragonal structure is only dynamically stable for early lan…
Crystal and Electronic Structure of GaTaSe From First-Principle Calculations
Shuai Zhang, Tiantian Zhang, Hongshan Deng +3
GaTaSe belongs to the lacunar spinel family. Its crystal structures is still a puzzle though there have been intensive studies on its novel properties, such as the Mott ins…
Coexistence of polar displacements and conduction in doped ferroelectrics: an ab initio comparative study
Chengliang Xia, Yue Chen, Hanghui Chen
Polar metals are rare because free carriers in metals screen electrostatic potential and eliminate internal dipoles. Degenerate doped ferroelectrics may create an approximate polar…
Large Thermal Motion in Halide Perovskites
T. A. Tyson, W. Gao, Y. -S. Chen +2
Solar cells based on hybrid perovskites have shown high efficiency while possessing simple processing methods. To gain a fundamental understanding of their properties on an atomic…
A first-principles approach to nonlinear lattice dynamics: Anomalous spectra in PbTe
Yue Chen, Xinyuan Ai, C. A. Marianetti
Here we introduce a new approach to compute the finite temperature lattice dynamics from first-principles via the newly developed slave mode expansion. We study PbTe where inelasti…
