Giant and Helical Exciton Dipole from Berry Curvature in Flat Chern Bands
Kaijie Yang, Huiyuan Zheng, Xiaodong Xu +2
We show that excitons forming between moiré flat Chern bands possess a substantial electric dipole moment comparable to the moiré lattice parameter times the elementary charge ($\s…
Orbital Hybridization-Induced Ising-Type Superconductivity in a Confined Gallium Layer
Hemian Yi, Yunzhe Liu, Chengye Dong +24
In low-dimensional superconductors, the interplay between quantum confinement and interfacial hybridization effects can reshape Cooper pair wavefunctions and induce novel forms of…
Symmetry-enforced Moiré Topology
Yunzhe Liu, Ethan Angerhofer, Kaijie Yang +2
Topological flat bands in two-dimensional (2D) moiré materials have emerged as promising platforms for exploring the interplay between topology and correlation effects. However, re…
Ideal Topological Flat Bands in Two-dimensional Moiré Heterostructures with Type-II Band Alignment
Yunzhe Liu, Anoj Aryal, Kaijie Yang +6
Topological flat bands play an essential role in inducing exotic interacting physics, ranging from fractional Chern insulators to superconductivity, in moiré materials. In this wor…
Interlayer Coupling-Induced Quantum Phase Transition in Quantum Anomalous Hall Multilayers
Ling-Jie Zhou, Deyi Zhuo, Ruobing Mei +8
A quantum phase transition arises from competition between different ground states and is typically accessed by varying a single physical parameter near absolute zero temperature.…
Engineering Miniband Topology via Band-Folding in Moiré Superlattice Materials
