Net and Hidden Spin-Valley Locking Enable Ultrahigh Hole Mobility in Covalent Bulk WN
Rong-Tian Pang, Zhongjuan Han, Jiayi Gong +3
High carrier mobility at room temperature underpins high-performance electronics, yet high hole mobility remains rare in bulk semiconductors. Spin-valley locking can suppress inter…
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…
Charge density wave in a band insulator
Md Shafayat Hossain, Wenhao Liu, Yuqi Zhang +20
Charge density wave (CDW) implies a periodic modulation of the charge density. Typically observed in metallic systems, CDWs arise from Fermi surface instabilities, resulting in the…
Unconventional Magnetism: Symmetry Classification, Hybrid-parity and Unconstrained-parity Classes
Xun-Jiang Luo, Dan Li, Rui-Chun Xiao +4
Unconventional magnetism has emerged as a transformative frontier in condensed matter physics. Such phases are characterized by substantial non-relativistic spin splitting (NSS) in…
Atomic-scale visualization of d-wave altermagnetism
Daran Fu, Liu Yang, Yi Shen +7
Altermagnetism is a newly identified magnetic phase, distinct from conventional ferromagnetism and antiferromagnetism. It exhibits no net magnetization while breaking time-reversal…
Magnetoresistance from decoherence
Xian-Peng Zhang, Yan-Qing Feng, Haiwen Liu +1
Microscopic theories of magnetoresistance have traditionally focused on momentum relaxation and the plasma frequency of itinerant electrons. Here, we uncover a distinct mechanism i…
