Stripe-Order Altermagnetism: Nematic Spin Splitting beyond the -Wave Classification
Zheng-Yang Zhuang, Zhongbo Yan
Altermagnetism combines compensated magnetic order with nonrelativistic spin splitting, yet established mechanisms predominantly rely on spin-reversing rotations in Néel-order ant…
Light-Induced Even-Wave Spin Splittings in Nonmagnetic Centrosymmetric Systems with Spin-Orbit Coupling
Xiao-Jiao Wang, Dongling Liu, Di Zhu +2
Spin splitting underpins a vast range of spin-dependent phenomena. Traditionally, two primary mechanisms generate such splitting: relativistic spin-orbit coupling (SOC) and nonrela…
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…
Odd-Parity Altermagnetism Originated from Orbital Orders
Zheng-Yang Zhuang, Di Zhu, Dongling Liu +2
Odd-parity spin-splitting plays a central role in spintronics and unconventional superconductivity, yet its microscopic realization in collinear magnetic systems remains elusive. W…
Light-induced odd-parity altermagnets on dimerized lattices
Dongling Liu, Zheng-Yang Zhuang, Di Zhu +2
Altermagnets are an emerging class of collinear magnets with momentum-dependent spin splitting and zero net magnetization. These materials can be broadly classified into two catego…
Floquet-Engineering Weyl Points and Linked Fermi Arcs from Straight Nodal Lines
Dongling Liu, Zheng-Yang Zhuang, Zhongbo Yan
Floquet engineering provides a powerful and flexible method for modifying the band structures of quantum materials. While circularly polarized light has been shown to convert curve…
