Superconductivity in non-centrosymmetric rhombohedral NbSe2
Zhengxian Li, Xiaoyu Shen, Kai Liu +14
Crystal stacking offers a powerful yet underexplored route to engineer symmetry in layered superconductors. Here we report superconductivity in rhombohedral-stacked NbSe2 (3R-NbSe2…
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,…
Unconventional Orbital Magnetism in Graphene-based Fractional Chern Insulators
Jian Xie, Zaizhe Zhang, Xi Chen +11
Orbital magnetism in graphene originates from correlation-driven spontaneous valley symmetry breaking1-7. It can lead to various anomalous transport phenomena such as integer and f…
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
