Displacement field-controlled fractional Chern insulators and charge density waves in a graphene/hBN moiré superlattice
Samuel H. Aronson, Tonghang Han, Zhengguang Lu +5
Rhombohedral multilayer graphene, with its flat electronic bands and concentrated Berry curvature, is a promising material for the realization of correlated topological phases of m…
Multi-Knob Switchable Chiral Superconductivity Quartet in Rhombohedral Graphene
Zhenqi Hua, Shenyong Ye, Phatthanon Pattanakanvijit +17
Chiral superconductors break orbital time-reversal symmetry and may host topological quasiparticles with non-Abelian statistics. In rhombohedral graphene, superconductivity develop…
Nanoscale control of rewriteable doping patterns in pristine graphene/boron nitride heterostructures
Jairo Velasco, Long Ju, Dillon Wong +11
Nanoscale control of charge doping in two-dimensional (2D) materials permits the realization of electronic analogs of optical phenomena, relativistic physics at low energies, and t…
Extended Quantum Anomalous Hall States in Graphene/hBN Moiré Superlattices
Zhengguang Lu, Tonghang Han, Yuxuan Yao +7
Electrons in topological flat bands can form novel topological states driven by the correlation effects. The penta-layer rhombohedral graphene/hBN moire superlattice has been shown…
Conservation law and Lie symmetry analysis of the (1+1) dimensional dispersive long-wave equation
Long Ju, Faiza Afzal, Yufeng Zhang
In this paper, we mainly study the integrability of 1+1 dimensional dispersive long-wave equation. Firstly, the Lie symmetry analysis of the equation is carried out in the first pa…
Fractional Quantum Anomalous Hall Effect in a Graphene Moire Superlattice
Zhengguang Lu, Tonghang Han, Yuxuan Yao +7
The fractional quantum anomalous Hall effect (FQAHE), the analog of the fractional quantum Hall effect1 at zero magnetic field, is predicted to exist in topological flat bands unde…
