Electric-Switchable Chiral Magnons in PT-Symmetric Antiferromagnets
Jinyang Ni, Congzhe Yan, Peiyuan Cui +3
The magnons in antiferromagnetic insulators (AFIs) exhibit dual chirality, each carrying opposite spin angular momentum. However, in PT-symmetric AFIs, the magnon bands remain dege…
Interlayer Charge-density-wave Vector Phase Induced Structural Chirality
Sen Shao, Wei-Chi Chiu, Tao Hou +21
Chiral charge density waves (CDWs) have attracted intense interest due to their exotic quantum properties, yet the microscopic origin of structural chirality emerging from correlat…
Wavefunction-Free Approach for Predicting Nonlinear Responses in Weyl Semimetals
Mohammad Yahyavi, Ilya Belopolski, Yuanjun Jin +15
By sidestepping the intractable calculations of many-body wavefunctions, density functional theory (DFT) has revolutionized the prediction of ground states of materials. However, p…
Magnon Nonlinear Hall Effect in 2D Antiferromagnetic Insulators
Jinyang Ni, Yuanjun Jin, Guoqing Chang
The efficient detection of the magnetism in 2D antiferromagnetic (AFM) insulators is crucial for the advancement of 2D AFM spintronics and remains a challenging problem. In this le…
Topological exciton bands and many-body exciton phases in transition metal dichalcogenide trilayer heterostructures
Ze-Hong Guo, Tao Yan, Jin-Zhu Zhao +2
Twisted multilayer transition metal dichalcogenides (TMDs) are a promising platform for realizing topological exciton phases. Here we propose that twisted TMD heterotrilayers WX$_2…
TensorSymmetry: a package to get symmetry-adapted tensors disentangling spin-orbit coupling effect and establishing analytical relationship with magnetic order
Rui-Chun Xiao, Yuanjun Jin, Zhi-Fan Zhang +3
The symmetry-constrained response tensors on transport, optical, and electromagnetic effects are of central importance in condensed matter physics because they can guide experiment…
