Realization of a Kondo Insulator in a Multilayer Moire Superlattice
Qiran Wu, Jingyuan Cui, Ang-Kun Wu +9
Kondo insulators are a paradigmatic strongly correlated electron system, arising from the hybridization between itinerary conduction electrons and localized magnetic moments, which…

Unconventional Fractional Phases in Multi-Band Vortexable Systems
Siddhartha Sarkar, Xiaohan Wan, Ang-Kun Wu +2
In this Letter, we study topological flat bands with distinct features that deviate from conventional Landau level behavior. We show that even in the ideal quantum geometry limit,…

Edge-driven transition between extended quantum anomalous Hall crystal and fractional Chern insulator in rhombohedral graphene multilayers
Zezhu Wei, Ang-Kun Wu, Miguel Gonçalves +1
Fractional Chern insulators (FCI) with fractionally quantized Hall conductance at fractional fillings and an extended quantum anomalous Hall (EQAH) crystal with an integer quantize…
