Piezo-Kerr effect in altermagnets and noncollinear antiferromagnets
Yuqi Liu, Qiu-Shi Huang, Xinfeng Chen +4
Symmetry is usually viewed as a constraint on physical responses, but it can also be used to design the fields that control them. Here, we adopt the representation-matching princip…
Fractional Spin Ferroelectric and Sliding Spin Current in Magnetic Sliding Ferroelectrics
Yilin Han, Lei Li, Chaoxi Cui +3
We investigate the fractional spin ferroelectric (FSFE) in magnetic sliding ferroelectrics (SFEs), where ferroelectric switching is characterized not only by the reversal of the ou…
Ridge-Spin-Layer Coupling and Emergent Ridgetronics in 2D Altermagnets
Mu Tian, Run-Wu Zhang, Chaoxi Cui +2
Extending valleytronics from discrete points to continuous lines in momentum space transforms dispersionless bands into a controllable degree of freedom. Here we introduce ridge--s…
Spin layer groups and their corepresentations
Zeying Zhang, Gui-Bin Liu, Mu Tian +3
Spin layer groups are the crystallographic symmetry groups with a periodic plane, and their symmetry operations are inherited from three-dimensional (3D) spin space groups. However…
Nonvolatile Electrical Control of Spin via Sliding Fractional Quantum Multiferroics
Jiajun Lu, Mu Tian, Chaoxi Cui +3
We propose a fractionally quantized polarization induced by interlayer sliding in bilayer altermagnets, unveiling a previously unrecognized multiferroic phase termed sliding fracti…
Switchable Giant Spin Injection Current in Janus Altermagnet FeSSeO
Fanxian Pei, Run-Wu Zhang, Lei Li +2
Generating and controlling spin current in miniaturized magnetic quantum devices remains a central objective of spintronics, due to its potential to enable future energy-efficient…
Symmetry Classification of Altermagnetism and Emergence of Type-IV Magnetism in Two Dimensions
Mu Tian, Chaoxi Cui, Zeying Zhang +3
Two-dimensional (2D) magnetism, particularly 2D altermagnetism (AM), has attracted considerable interest due to its exceptional physical properties and broad application potential.…
Type-II Antiferroelectricity
Yang Wang, Zhi-Ming Yu, Chaoxi Cui +6
Antiferroelectricity (AFE) is a fundamental concept in physics and materials science. Conventional AFEs have the picture of alternating local electric dipoles defined in real space…
Mirror real Chern insulator in two and three dimensions
Yang Wang, Chaoxi Cui, Run-Wu Zhang +4
A real Chern insulator (RCI) featuring a real Chern number and a second-order boundary mode appears in a two-dimensional (2D) system with the space-time inversion symmetry (PT ). H…
Quasi-one-dimensional spin transport in altermagnetic nodal net metals
Tingli He, Lei Li, Chaoxi Cui +4
In three dimensions, quasi-one-dimensional (Q1D) transport has traditionally been associated with systems featuring a Q1D chain structure. Here, based on first-principle calculatio…
Topological quantum phase transition in the magnetic semimetal HoSb
Jian-Min Zhang, Fang Tang, Yurong Ruan +14
Magnetic topological semimetals, a novel state of quantum matter with nontrivial band topology, have emerged as a new frontier in physics and materials science. An external stimulu…
