Twistronics in graphene-based van der Waals structures
Ya-Ning Ren, Yu Zhang, Yi-Wen Liu +1
The electronic properties of van der Waals (vdW) structures can be substantially modified by the moire superlattice potential, which strongly depends on the twist angle among the c…
Pseudospin-mediated Atomic-scale Vortices and Their Quantum Interferences in Monolayer Graphene
Yu Zhang, Lin He
Vortex is a universal and significant phenomenon that has been known for centuries. However, creating vortices to the atomic limit has remained elusive because that the characteris…
Tunable lattice reconstruction and bandwidth of flat bands in magic-angle twisted bilayer graphene
Yi-Wen Liu, Ying Su, Xiao-Feng Zhou +10
The interplay between interlayer van der Waals interaction and intralayer lattice distortion can lead to structural reconstruction in slightly twisted bilayer graphene (TBG) with t…
Robust two-dimensional ice on graphene built from finite-length water molecular chains
Sheng Han, Jia-Bin Qiao, Lin-Fang Hou +7
Interfacial ice on graphene has attracted much attention because it is a model system to study two-dimensional (2D) ice structures on chemically inert substrates. While water-graph…
Intervalley quantum interference and measurement of Berry phase in bilayer graphene
Yu Zhang, Ying Su, Lin He
Chiral quasiparticles in Bernal-stacked bilayer graphene have valley-contrasting Berry phases of 2π. This nontrival topological structure, associated with the pseudospin winding al…
Chiral SO(4) spin-valley density wave and degenerate topological superconductivity in magic-angle-twisted bilayer-graphene
Chen Lu, Yongyou Zhang, Yu Zhang +6
Starting from a realistic extended Hubbard model for a -orbital tight-binding model on the Honeycomb lattice, we perform a thorough investigation on the possible electron…
Electron interactions in strain-induced zero-energy flat band in twisted bilayer graphene near the magic angle
Yu Zhang, Zhe Hou, Ya-Xin Zhao +6
In the vicinity of the magic angle in twisted bilayer graphene (TBG), the two low-energy van Hove singularities (VHSs) become exceedingly narrow1-10 and many exotic correlated stat…
Nanoscale Probing of Broken-Symmetry States in Graphene Induced by Individual Atomic Impurities
Yu Zhang, Qi-Qi Guo, Si-Yu Li +1
Inherent symmetries of a system lead to multiple degeneracies of its energy spectra. Introducing individual atomic impurities can locally break these symmetries, which is expected…
