Spin-canting-induced Giant Nonlinear Optical Magnetochirality in a 2D Ferrotoroid
Shian Xia, Sheng Liu, Wenhe Jia +9
The paper demonstrates giant nonlinear optical magnetochirality in bilayer CrSBr, where a field‑induced spin‑canting breaks PT symmetry and enables magnetically switchable circular…
Ridge-Spin-Layer Coupling and Emergent Ridgetronics in 2D Altermagnets
Mu Tian, Run-Wu Zhang, Chaoxi Cui +2
The paper proposes ridge‑spin‑layer coupling in two‑dimensional altermagnets, where a one‑dimensional line of dispersionless electronic states (a ridge) is locked to spin polarizat…
Curvature Converts Phonon Hall Viscosity into Phonon Angular Momentum
Pablo A. Morales
The paper shows that static curvature in thin crystalline membranes enables phonon Hall viscosity to generate in‑plane phonon angular momentum, leading to a measurable torque propo…
Multistate ferroelectricity and switchable layer-locked anomalous valley Hall effects in bilayer ReIrGe2Se6
Tao Yao, Quan Shen, Jianing Tan +1
The paper predicts, via first‑principles calculations, that bilayer ReIrGe2Se6 exhibits four stable ferroelectric states whose switching controls layer‑locked anomalous valley Hall…
Interlayer sliding direction as a symmetry selector in altermagnetic bilayer Fe2WS4: Switchable anomalous Hall and anomalous valley Hall effects
Quan Shen, Jianing Tan, Tao Yao +2
The paper shows that sliding the layers of a 2D altermagnetic Fe2WS4 bilayer can reversibly switch its ferroelectric polarization, spin texture, and associated anomalous Hall and v…
Revealing the MoS2 Growth Mechanism in Chemical Vapor Deposition: Real-Time Imaging and Statistical Analysis
Faizal Arifurrahman, Tianshu Zhai, Yuguo Wang +4
The paper presents a semi‑automated image‑processing workflow that tracks the real‑time growth of over 400 MoS2 crystals during chemical vapor deposition, revealing that growth is…
