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…
Doping-induced Quantum Anomalous Hall Crystals and Topological Domain Walls
Miguel Gonçalves, Shi-Zeng Lin
Doping carriers into a correlated quantum ground state offers a promising route to generate new quantum states. The recent advent of moiré superlattices provided a versatile platfo…
Quantum-metric-induced quantum Hall conductance inversion and reentrant transition in fractional Chern insulators
Ang-Kun Wu, Siddhartha Sarkar, Xiaohan Wan +2
The quantum metric of single-particle wave functions in topological flatbands plays a crucial role in determining the stability of fractional Chern insulating (FCI) states. Here, w…
Contrasting twisted bilayer graphene and transition metal dichalcogenides for fractional Chern insulators: an emergent gauge picture
Heqiu Li, Ying Su, Yong Baek Kim +3
The recent experimental discovery of the zero-field fractional Chern insulator (FCI) in twisted moiré superlattices has sparked immense interest in this exotic to…
