Observation of interaction-induced fast Thouless pumping of solitons
Yuqing Li, Jinxiong Jia, Yunfei Wang +7
Thouless pumping provides a paradigmatic platform for studying the effects of interactions on topological transport in periodically driven systems. However, most studies have been…
Anisotropic Gyromagnetic Ratio and Orthogonal Einstein-de Haas Effect
Rui Xue, Zhenhua Qiao, Yang Gao +1
We theoretically demonstrate an orthogonal Einstein-de Haas effect, where the rotation of ferromagnetic materials is caused by the change of magnetization in the direction orthogon…
Pressure-Driven Moiré Potential Enhancement and Tertiary Gap Opening in Graphene/h-BN Heterostructure
Yupeng Wang, Jiaqi An, Chunhui Ye +13
Moiré superlattices enable engineering of correlated quantum states through tunable periodic potentials, where twist angle controls periodicity but dynamic potential strength modul…
Quantum Anomalous Hall Effect in Flat Bands with Paramagnetism
Yedi Shen, Sanyi You, Zhenhua Qiao +1
Quantum anomalous Hall effect has been widely explored in both ferromagnetic and antiferromagnetic systems. Here, we propose an interaction-driven paramagnetic quantum anomalous Ha…
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…
Extrinsic Mechanisms of Phonon Magnetic Moment
Rui Xue, Zhenhua Qiao, Yang Gao +1
We develop a general formalism of phonon magnetic moment by including the relaxation process. We then identify the skew-scattering and side-jump contributions to the phonon magneti…
Engineering second-order topological insulators via coupling two first-order topological insulators
Lizhou Liu, Jiaqi An, Yafei Ren +3
We theoretically investigate the engineering of two-dimensional second-order topological insulators with corner states by coupling two first-order topological insulators. We find t…
Chern Number Tunable Quantum Anomalous Hall Effect in Compensated Antiferromagnets
Wenhao Liang, Jiaqi An, Zeyu Li +3
We propose to realize the quantum anomalous Hall effect (QAHE) in two-dimensional compensated antiferromagnets without net spin magnetization.} We consider antiferromagnetic MnBi$_…
