From fractional Chern insulators to topological electronic crystals in moiré MoTe2: quantum geometry tuning via remote layer
Feng Liu, Fan Xu, Cheng Xu +18
The quantum geometry of Bloch wavefunctions,encoded in the Berry curvature and quantum metric, is believed to be a decisive ingredient in stabilizing fractional quantum anomalous H…
Tunable Luttinger liquid and correlated insulating states in one-dimensional moiré superlattices
Jiajun Chen, Bosai Lyu, Liguo Wang +23
Two-dimensional moiré superlattices have been extensively studied, and a variety of correlated phenomena have been observed. However, their lower-dimensional counterpart, one-dimen…
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…
Moiré enhanced flat band in rhombohedral graphene
Hongyun Zhang, Jinxi Lu, Kai Liu +17
The fractional quantum anomalous Hall effect (FQAHE) is a fascinating emergent quantum state characterized by fractionally charged excitations in the absence of magnetic field,whic…
