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…
The Price of Precision: A Calibrated Cost Model for Mixed-Precision LLM Serving
Mukund Athmaram, Manoj Rao, Liang Ma
Choosing a mixed-precision configuration for large language model (LLM) serving trades speed against accuracy. Allocators that use average bit-width or a memory budget as a speed p…
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…
Unconventional Scaling of Electric Hall Effect in Magnetic Weyl Semimetals
Chaoxi Cui, Yilin Han, Run-Wu Zhang +2
Electric Hall Effect (EHE), a unique phenomenon in two-dimensional (2D) magnetic systems, refers to the generation of Hall current by an out-of-plane electric field $\Ez$. Here, we…
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…

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…
Anomalous Hall Effect in Type IV 2D Collinear Magnets
Ling Bai, Run-Wu Zhang, Wanxiang Feng +1
We identify a previously unrecognized class of two-dimensional (2D) collinear magnetic phase that extends beyond the established categories of ferromagnets, antiferromagnets, and a…
Quantized Spin-Hall Conductivity in Altermagnet FeTeO with Mirror-Spin Coupling
Run-Wu Zhang, Chaoxi Cui, Yang Wang +3
Due to spin-orbit coupling (SOC), crucial for the quantum spin Hall (QSH) effect, a quantized spin-Hall conductivity has not yet been reported in QSH insulators and other realistic…
