Honeycomb Crystal in a Mass-Asymmetric Electron-Hole Bilayer
Shengdu Chai, Wangqian Miao, Yuqiang Li +3
A two-dimensional electron gas in a uniform neutralizing background forms a triangular Wigner crystal at low density. In a strongly mass-asymmetric electron-hole bilayer, localized…
Cooper Instability of a Magnetic Wigner Crystal
Wangqian Miao, Chunli Huang
Recent scanning tunneling microscopy has directly imaged electronic crystals in rhombohedral hexalayer graphene, and magnetotransport measurements suggest that superconductivity an…
Gauge-covariant magnetic Bloch sums for general multiorbital Hofstadter models
Hao Shi, Tianyu Qiao, Wangqian Miao +3
We formulate a unified treatment of the Hofstadter problem for general two-dimensional multiorbital Peierls tight-binding Hamiltonians using a gauge-covariant magnetic Bloch-sum ba…
Retarded interaction between opposite chiral edges in anomalous Hall crystals
Wangqian Miao, Mu-Yang Chen, Binghai Yan +1
An anomalous Hall crystal combines spontaneous electronic crystallization with a Chern insulating gap, supporting both chiral edge modes and low-energy electronic phonons. We show…
Emergence of Topological Electron Crystals in Bilayer Graphene--Mott Insulator Heterostructures
Wangqian Miao, Tianyu Qiao, Xue-Yang Song +4
The interplay between strong electron correlation and band topology offers a playground for discovering exotic quantum phases. Here, we predict the emergence of topological electro…

Wangqian Miao, Chu Li
We systematically investigate the emergence of electron crystal phases in rhombohedral multilayer graphene using comprehensive self-consistent Hartree Fock calculations combined wi…
Universal Moiré-Model-Building Method without Fitting: Application to Twisted MoTe and WSe
Yan Zhang, Hanqi Pi, Jiaxuan Liu +8
We develop a comprehensive method to construct analytical continuum models for moiré systems directly from first-principle calculations without any parameter fitting. The core idea…
Artificial moiré engineering for an ideal BHZ model
Wangqian Miao, Arman Rashidi, Xi Dai
We demonstrate that (001) grown Cd3As2 thin films with a superlattice-patterned gate can potentially realize the moiré Bernevig-Hughes-Zhang (BHZ) model. Our calculations identify…
Moiré optical phonons dancing with heavy electrons in magic-angle twisted bilayer graphene
Hao Shi, Wangqian Miao, Xi Dai
Electron-phonon coupling in magic-angle twisted bilayer graphene is an important but difficult topic. We propose a scheme to simplify and understand this problem. Weighted by the c…
Engineering the in-plane anomalous Hall effect in CdAs thin films
Wangqian Miao, Binghao Guo, Susanne Stemmer +1
We predict two topological phase transitions for cadmium arsenide (\ce{Cd3As2}) thin films under in-plane magnetic field, taking advantage of a four-band model and effec…
Zeeman field-induced two-dimensional Weyl semimetal phase in cadmium arsenide
Binghao Guo, Wangqian Miao, Victor Huang +3
We report a topological phase transition in quantum-confined cadmium arsenide (Cd3As2) thin films under an in-plane Zeeman field when the Fermi level is tuned into the topological…
Strong Inter-valley Electron-Phonon Coupling in Magic-Angle Twisted Bilayer Graphene
Cheng Chen, Kevin P. Nuckolls, Shuhan Ding +31
The unusual properties of superconductivity in magic-angle twisted bilayer graphene (MATBG) have sparked enormous research interest. However, despite the dedication of intensive ex…

Wangqian Miao, Chu Li, Xu Han +2
We propose a highly efficient and accurate numerical scheme named Truncated Atomic Plane Wave (TAPW) method to determine the subband structure of Twisted Bilayer Graphene (TBG) ins…
