Supermoiré Chern mosaic in helical trilayer WSe2
Zhenyu Wang, Mingjie Zhang, Hai Meng +19
Helically twisted multilayers offer access to moiré physics beyond the single-superlattice paradigm, yet their correlated and topological transport properties remain largely unexp…
Signatures of unconventional superconductivity near reentrant and fractional quantum anomalous Hall insulators
Fan Xu, Zheng Sun, Jiayi Li +18
Two-dimensional moiré Chern bands provide an exceptional platform for exploring a variety of many-body quantum phases at zero magnetic field within a lattice system. One particula…
Observation of sequential quantum oscillations induced by mini-Landau bands in a three-dimensional Dirac semiconductor
Zezhi Wang, Dong Xing, Bingbing Tong +5
Quantum oscillations, the oscillatory behavior of electrical and thermodynamic properties, are typically observed in metals and vanish in the quantum limit under strong magnetic fi…
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…
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…
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,…
