Frustration from Localized Zhang-Rice States: A Unified Theory of Doping-Driven Magnetic Transitions in Cuprates
Xiaodong Wang, Ping Xu, Jiong Mei +5
The microscopic mechanism by which doped holes disrupt the antiferromagnetic order is one of the fundamental questions in cuprates. In this work, we propose a unified microscopic t…
Two-dimensional alternating ferrimagnetism with strain-controlled half-metallic state and valley polarization
W. Z. Zhuo, Z. H. Guan, Z. L. Peng +4
The discovery of altermagnetism offers new opportunities for exploring novel quantum states and developing spintronic devices for enabling momentum dependent spin splitting in comp…
Magnetic electron-hole asymmetry in cuprates: a computational revisit
Jiong Mei, Shao-Hang Shi, Ping Xu +5
In this work, we revisit the electron-hole asymmetry of antiferromagnetism in cuprates by studying the three-band Emery model. Using parameters relevant to LaCuO, we benchm…
Anderson localization: a density matrix approach
Ziyue Qi, Yi Zhang, Mingpu Qin +2
Anderson localization is a quantum phenomenon in which disorder localizes electronic wavefunctions. In this work, we propose a new approach to study Anderson localization based on…
