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…
Discovery of Van Hove Singularities: Electronic Fingerprints of 3Q Magnetic Order in a van der Waals Quantum Magnet
Hai-Lan Luo, Josue Rodriguez, Debasis Dutta +11
Magnetically intercalated transition metal dichalcogenides are emerging as a rich platform for exploring exotic quantum states in van der Waals magnets. Among them, CoxTaS2 has att…
Complex Refractive Index Extraction for Spintronic Terahertz Emitter Analysis
Yingshu Yang, Keynesh Dongol, Stefano Dal Forno +7
Spintronic terahertz emitters (STEs) generate broadband terahertz (THz) radiation, which is essential for spectroscopy, imaging, and communication. The performances and the essenti…
Competitive Orders in Altermagnetic Chiral Magnons
Congzhe Yan Zhijun Jiang Jinyang Ni, Guoqing Chang
The magnons in altermagnets exhibit chiral splitting even in the absence of spin-orbit coupling and external magnetic fields. Typically, this chiral splitting behavior can be well…
