A Unified Symmetry Classification of Magnetic Orders via Spin Space Groups: Prediction of Coplanar Even-Wave Phases
Ziyin Song, Ziyue Qi, Chen Fang +2
Spin space groups (SSGs) impose fundamentally different constraints on magnetic configurations in real and reciprocal spaces. As a consequence, the correspondence between real-spac…
Chern-Selective multi-valley Flat Bands in Twisted Mono-Bilayer and Mono-Trilayer MoTe
Ziyue Qi, Hanqi Pi, Yan Zhang +6
The interplay between moiré flat bands originating from different valleys can give rise to a variety of exotic quantum phases. In this work, we investigate the electronic propertie…
Anderson localization: a density matrix approach
Ziyue Qi, Yi Zhang, Mingpu Qin +2
Anderson localization is a quantum phenomenon in which disorder localizes electronic wavefunctions. In this work, we propose a new approach to study Anderson localization based on…
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…
Majorana zero modes under electron correlation
Ziyue Qi, Hongming Weng, Kun Jiang
In this work, we perform a systematic investigation of the correlated topological superconductors (TSCs), especially their non-trivial Majorana zero modes (MZMs). Compared to the n…
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…
The destiny of obstructed atomic insulator under correlation
Kun Jiang, Hongming Weng, Jiangping Hu
The obstructed atomic insulators are insulators with both atomic limits and boundary states. In this work, we study the obstructed atomic insulators under correlation. We use the s…
