Quantum Anomalous Hall Effect in Oxide Monolayers
Zeyu Li, Xudong Zhu, Yulei Han +1
Quantum anomalous Hall effect (QAHE) arises from the interplay between magnetic order and spin-orbit coupling, which opens up a topologically nontrivial band gap to host chiral edg…
The Layer Hall Effect without External Electric Field
Yulei Han, Yunpeng Guo, Zeyu Li +1
The layer Hall effect is an intriguing phenomenon observed in magnetic topological layered materials, where the Hall response arises from the opposite deflection of electrons on to…
Altermagnetism Induced Topological Phase Transitions in Kane-Mele Model
Zhengtian Li, Zeyu Li, Zhenhua Qiao
We theoretically demonstrate that Chern number tunable quantum anomalous Hall effect (QAHE) and second-order topological insulators can be induced in the two-dimensional $\mathbb{Z…
Electric-field-tunable topological phases in valley-polarized quantum anomalous Hall systems with inequivalent exchange fields
Shiyao Pan, Zeyu Li, Yulei Han
Incorporating valley as a degree of freedom into quantum anomalous Hall systems offers a novel approach to manipulating valleytronics in electronic transport. Using the Kane-Mele m…
Chern Number Tunable Quantum Anomalous Hall Effect in Compensated Antiferromagnets
Wenhao Liang, Jiaqi An, Zeyu Li +3
We propose to realize the quantum anomalous Hall effect (QAHE) in two-dimensional compensated antiferromagnets without net spin magnetization.} We consider antiferromagnetic MnBi$_…
Disorder-Induced Phase Transitions in Three-Dimensional Chiral Second-Order Topological Insulator
Yedi Shen, Zeyu Li, Qian Niu +1
Topological insulators have been extended to higher-order versions that possess topological hinge or corner states in lower dimensions. However, their robustness against disorder i…
Chern Number Tunable Quantum Anomalous Hall Effect in Monolayer Transitional Metal Oxides via Manipulating Magnetization Orientation
Zeyu Li, Yulei Han, Zhenhua Qiao
Although much effort has been made to explore quantum anomalous Hall effect (QAHE) in both theory and experiment, the QAHE systems with tunable Chern numbers are yet limited. Here,…
Large Rashba Spin-Orbit Coupling and High-Temperature Quantum Anomalous Hall Effect in Re-Intercalated Graphene/CrI Heterostructure
Yulei Han, Zhi Yan, Zeyu Li +4
In 2010, quantum anomalous Hall effect (QAHE) in graphene was proposed in the presence of Rashba spin-orbit coupling and ferromagnetic exchange field. After a decade's experimental…
Large-Gap Quantum Anomalous Hall Effect in Monolayer Halide Perovskite
Zeyu Li, Yulei Han, Zhenhua Qiao
We theoretically propose a family of structurally stable monolayer halide perovskite ABC (A=Rb, Cs; B=Pd, Pt; C=Cl, Br) with easy magnetization planes. These materials…
