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…
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…
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…
MoireStudio: A Universal Twisted Electronic Structure Calculation Package
Junxi Yu, Yichen Liu, Cheng-Cheng Liu
Twistronics is an emerging and captivating field in condensed matter physics and material science. However, accurately and efficiently calculating the electronic structures of twis…
Unconventional Magneto-Optical Effects in Altermagnets
Yongpan Li, Yichen Liu, Cheng-Cheng Liu
The ideal altermagnets are a class of collinear, crystal-symmetry-enforced fully compensated magnets with nonrelativistic spin-split bands, in which contributions from Berry curvat…
