Cascade of Even-Denominator Fractional Quantum Hall States in Mixed-Stacked Multilayer Graphene
Yating Sha, Kai Liu, Chenxin Jiang +15
The fractional quantum Hall effect (FQHE), particularly at half-filling of Landau levels, provides a unique window into topological phases hosting non-Abelian excitations. However,…
Intrinsic layer polarization and multi-flatband transport in non-centrosymmetric mixed-stacked multilayer graphene
Kai Liu, Yating Sha, Bo Yin +20
Graphene multilayers exhibit electronic spectra that depend sensitively on both the number of layers and their stacking order. Beyond trilayer graphene, mixed stacking sequences (a…
Stacking-orientation and twist-angle control on integer and fractional Chern insulators in moiré rhombohedral graphene
Chushan Li, Chuanqi Zheng, Kai Liu +24
Rhombohedral-stacked multilayer graphene aligned with hexagonal boron nitride has emerged as an excellent platform for investigating exotic quantum phenomena arising from the inter…
Electrical switching of Chern insulators in moire rhombohedral heptalayer graphene
Zhiyu Wang, Qianling Liu, Xiangyan Han +14
In orbital Chern insulators, the chemical potential acts as a tuning knob to reverse chirality in dissipationless edge currents, enabling electric-field control of magnetic order-k…
