Field-induced asymmetric band flattening and ideal quantum geometry in rhombohedral graphene
Hongyun Zhang, Jinxi Lu, Size Wu +17
Rhombohedral graphene exhibits an exceptionally diverse array of correlated phases that depend sensitively on the displacement field. Compiling reported phases into a unified phase…
Observation of Floquet-induced gap in graphene
Fei Wang, Xuanxi Cai, Xiao Tang +8
Floquet engineering provides a powerful pathway for creating non-equilibrium phases of matter with tailored electronic structures and properties through time-periodic driving. As t…
Moiré-modulated valley in twisted bilayer and twisted double-bilayer MoTe
Wanying Chen, Hongyun Zhang, Jinxi Lu +18
Twisted MoTe hosts intriguing correlated quantum phenomena including the fractional quantum anomalous Hall effect in twisted bilayer (t-BL) MoTe near 3.7, which is…
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…
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…
