Complete Hierarchy of Nonrelativistic Odd-Parity Spin Splitting in Collinear Magnets
Yichen Liu, Junxi Yu, Pu Zhang +1
Momentum-dependent nonrelativistic spin splitting provides a symmetry fingerprint of collinear magnets and can govern unconventional electronic, magnonic, and transport phenomena.…
Quantum metric-induced generalized magneto-optical effects in -symmetric antiferromagnets
Yongpan Li, Yichen Liu, Cheng-Cheng Liu
The magneto-optical effects (MOEs), as fundamental physical phenomena, can reveal the electronic structures of materials. The related probing methods are widely used in the study o…
Linearly Polarized Light-Induced Anomalous Hall Effect and Topological Phase Transitions in an Altermagnetic Topological Insulator
Yichen Liu, Tongshuai Zhu, Haijun Zhang
A recently identified class of collinear magnetic order, characterized by vanishing net magnetization yet unconventional spin splitting, known as altermagnets (AMs), has attracted…
Odd-Parity Magnons
Pu Zhang, Sun-Bo Xie, Junxi Yu +2
Magnons, as charge-neutral spin excitations, can transport spin information without Joule heating and therefore offer a promising platform for low-power spintronics. However, in co…
Spontaneous Fully Compensated Ferrimagnetism
Bingbing Wang, Yongpan Li, Yichen Liu +1
We propose a general mechanism for the spontaneous emergence of filling-enforced fully compensated ferrimagnetism (fFIM), characterized by zero net magnetization yet ferromagnetic-…
Antiferroaxial altermagnetism
Yichen Liu, Cheng-Cheng Liu
The antiferroaxial state is emerging as an important ferroic order in condensed matter systems. Here, we establish antiferroaxial altermagnetism as a broadly prevalent, generic, an…
