Electronic states at twist stacking faults in rhombohedral graphite
Xiaoqian Liu, Yifei Guan, Oleg V. Yazyev
Flat bands in graphitic materials emerged as a platform for realizing tunable correlated physics. As a nodal-line semimetal, rhombohedral graphite features flat drumhead surface st…
Fully First-Principles Approach in Studying Topological Magnons
Xiaoqiang Liu, Ji Feng, Zhenhua Qiao +1
We develop a fully first-principles approach for spin dynamics based on density functional perturbation theory. We demonstrate that the magnon wavefunction can be expressed by a se…
A Recursive Hybrid Tetrahedron Method for Brillouin-zone Integration
Kun Dong, Yihao Lin, Xiaoqiang Liu +2
A recursive extension of the hybrid tetrahedron method for Brillouin-zone integration is proposed, allowing iterative tetrahedron refinement and significantly reducing the error fr…
Berry phases in Coulomb drag of double-layer graphene system
Jianghui Pan, Lijun Zhu, Xiaoqiang Liu +3
Recent experiments suggest quantum interference effects in the Coulomb drag of double-layer graphene systems. By accounting for correlated interlayer impurity scattering under a we…
Exploration of magnetoelastic deformations in spin-chain compound CuBr
Biaoyan Hu, Yingying Peng, Xiaoqiang Liu +7
We investigate a spin- antiferromagnet, CuBr, which has quasi-one-dimensional structural motifs. The system has previously been observed to exhibit unusual Raman m…
