Quantum Geometry-Driven RKKY: From Flat to Dispersive Bands
Zhenggang Zhou, Chuang Li, Lun-Hui Hu
The paper investigates how the RKKY magnetic exchange behaves in isolated flat-band systems, showing that its decay length is governed by the quantum metric and band gap and can va…
Andreev Reflection to Probe Momentum-Dependent Spin Polarization in Altermagnet CrSb
Yan Zhang, Yixuan Luo, Yue Yang +7
Altermagnetic materials have recently emerged as promising candidates for next-generation spintronic applications, characterized by the k-dependent spin-splitted band structure and…
Observation of hidden altermagnetism in CsVTeO
Guowei Yang, Ruihan Chen, Changchao Liu +25
Altermagnets are characterized by anisotropic band/spin splittings in momentum space, dictated by their spin-space group symmetries. However, the real-space modulations of altermag…
Mixed-Parity Altermagnetism in Collinear Spin-Orbital Magnets
Zheng-Yang Zhuang, Jin-Xin Hu, Song-Bo Zhang +2
Altermagnetism has so far mainly been understood in its even- and odd-parity forms. We show that collinear antiferromagnets with zero net magnetization can also host mixed-parity s…
Finite-momentum mixed singlet-triplet pairing in chiral antiferromagnets induced by even-parity spin texture
Song-Bo Zhang, Lun-Hui Hu
Non-relativistic spin-splitting in unconventional antiferromagnets has garnered much attention for its promising spintronic applications and open fundamental questions. Here, we un…
Altermagnetic Even-Odd Effects in CsVTeO Josephson Junctions
Chuang Li, Jin-Xing Hou, Shuai-Ling Zhu +5
The interplay between conventional superconductivity and unconventional magnetism offers an exciting platform for realizing exotic superconducting phenomena. Here, we investigate J…
