Gradient-based optimization of non-Abelian fractional quantum states in patterned superlattices
Yifei Guan, Lichen Yu, Zizhuang Liu +2
The realization of fractional Chern insulator (FCI) states in moiré heterostructures has attracted intense interest in the study of correlated topological states. So far, most expe…
Charge imprinting biases topology of correlated insulator in hBN-aligned rhombohedral multilayer graphene
Lei Qiao, Xin Lu, Fu-Chun Zhang +1
Rhombohedral multilayer graphene aligned with hexagonal boron nitride (RMG-hBN) hosts correlated Chern phases, but the microscopic role of hBN stacking remains unclear, especially…
Fractional topological states in rhombohedral multilayer graphene modulated by kagome superlattice
Yanran Shi, Bo Xie, Fengfan Ren +7
Fractional quantum anomalous Hall effects realized in twisted bilayer MoTe and multilayer-graphene-based moiré heterostructures have captured a tremendous growth of interest. I…
Orbital magnetoelectric coupling of three dimensional Chern insulators
Xin Lu, Renwen Jiang, Zhongqing Guo +1
