Chiral superconductors and competing states across a Lifshitz transition in rhombohedral pentalayer graphene
Chuanqi Zheng, Cheng Xu, Chushan Li +19
Rhombohedral multilayer graphene hosts a distinctive low-energy electronic structure in which strong Coulomb interactions and nontrivial quantum geometry intertwine to generate exo…

Tunable high-Chern-number Chern insulators in rhombohedral tetralayer graphene/hBN moiré superlattices
Chuanqi Zheng, Chushan Li, Ke Huang +17
Moiré superlattices based on rhombohedral multilayer graphene have emerged as a highly tunable platform for engineering correlated topological phases. Here, we systematically inves…
