Generalized Space Groups from Internal Configuration Spaces
Zeying Zhang, Zhenye Li, Zhi-Ming Yu +2
We develop a unified construction of generalized space groups for crystals with unconventional internal degrees of freedom. Starting from the full group of allowed internal t…
Nonmagnetic-magnetic Transitions in Rutile RuO2
Yue-Fei Hou, Siyuan Liu, Wanxiang Fen +4
Rutile RuO has recently attracted great interest, as its magnetic ground state remains controversial. Experimental studies have reported either nonmagnetic (NM) or altermagneti…
Spin layer groups and their corepresentations
Zeying Zhang, Gui-Bin Liu, Mu Tian +3
Spin layer groups are the crystallographic symmetry groups with a periodic plane, and their symmetry operations are inherited from three-dimensional (3D) spin space groups. However…
Giant Magneto-Optical Effects in Two-Dimensional Flat-Band Antiferromagnets
Ping Yang, Wanxiang Feng, Siyuan Liu +5
In this work, we reveal giant magneto-optical responses in two-dimensional(2D) antiferromagnets with nearly flat electronic bands, based on first-principles calculations and group-…
