Relative hybridization textures as local coordinates for band geometry and topology
Caiyuan Ye, Zhong Fang, Hongming Weng +1
Global diagnostics such as Berry curvature and quantum metrics characterize the geometry and topology of an occupied Bloch subspace, leaving the microscopic sectors that carry this…
High-Chern-number Quantum anomalous Hall insulators in mixing-stacked MnBiTe thin films
Jiaheng Li, Quansheng Wu, Hongming Weng
Quantum anomalous Hall (QAH) insulators are characterized by vanishing longitudinal resistance and quantized Hall resistance in the absence of an external magnetic field. Among the…
Observation of topological Anderson Chern insulator phase in MnBiTe monolayer
Anqi Wang, Bo Yin, Zikang Su +23
The correlation of topology and disorder has attracted great intention due to appropriate disorder could induce the phase transition between trivial and nontrivial topological stat…
DPmoire: A tool for constructing accurate machine learning force fields in moiré systems
Jiaxuan Liu, Zhong Fang, Hongming Weng +1
In moiré systems, the impact of lattice relaxation on electronic band structures is significant, yet the computational demands of first-principles relaxation are prohibitively high…
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…
Observation of dichotomic field-tunable electronic structure in twisted monolayer-bilayer graphene
Hongyun Zhang, Qian Li, Youngju Park +18
Twisted bilayer graphene (tBLG) provides a fascinating platform for engineering flat bands and inducing correlated phenomena. By designing the stacking architecture of graphene lay…
Moiré Fractional Chern Insulators II: First-principles Calculations and Continuum Models of Rhombohedral Graphene Superlattices
Jonah Herzog-Arbeitman, Yuzhi Wang, Jiaxuan Liu +10
The experimental discovery of fractional Chern insulators (FCIs) in rhombohedral pentalayer graphene twisted on hexagonal boron nitride (hBN) has preceded theoretical prediction. S…
Moiré Fractional Chern Insulators I: First-principles calculations and Continuum Models of Twisted Bilayer MoTe
Yujin Jia, Jiabin Yu, Jiaxuan Liu +6
Recent experiments observed fractional Chern insulators (FCI) in twisted bilayer MoTe at zero magnetic field, yet even the single-particle model of this material is controversi…
