Emergent trans-moiré orbitals and topology in rhombohedral graphene
Yuqin Wang, Jian Xie, Yi-Jie Wang +13
The fractional quantum anomalous Hall effect (FQAHE) exhibited in fractional Chern insulators has recently been demonstrated in twisted MoTe2 and rhombohedral graphene/hBN moiré su…
Unconventional Orbital Magnetism in Graphene-based Fractional Chern Insulators
Jian Xie, Zaizhe Zhang, Xi Chen +11
Orbital magnetism in graphene originates from correlation-driven spontaneous valley symmetry breaking1-7. It can lead to various anomalous transport phenomena such as integer and f…
Stable Real-Space Invariants and Topology Beyond Symmetry Indicators
Yoonseok Hwang, Vaibhav Gupta, Frank Schindler +4
We introduce stable real-space invariants (SRSIs), topological invariants defined from adiabatic deformations between Wannier states, generalizing previously discovered local and c…
Projected and Solvable Topological Heavy Fermion Model of Twisted Bilayer Graphene
Haoyu Hu, Zhi-Da Song, B. Andrei Bernevig
We investigate the topological heavy-fermion (THF) model of magic-angle twisted bilayer graphene (MATBG) in the projected limit, where only the flat bands are present in the low-en…
Intrinsic (Axion) Statistical Topological Insulator
Xi Chen, Fa-Jie Wang, Zhen Bi +1
Ensembles that respect symmetries on average exhibit richer topological states than those in pure states with exact symmetries, leading to the concept of average symmetry-protected…
Ring states in topological materials
Raquel Queiroz, Roni Ilan, Zhida Song +2
Ingap states in semiconductors are commonly characterized by hydrogenic models within the effective mass approximation. However, when impurities are strong, this description fails.…
Topological Heavy Fermion Principle For Flat (Narrow) Bands With Concentrated Quantum Geometry
Jonah Herzog-Arbeitman, Jiabin Yu, Dumitru Călugăru +8
We propose a general principle for the low-energy theory of narrow bands with concentrated Berry curvature and Fubini-Study metric in the form of a map to Anderson-"+" models compo…
Dynamical Symmetry Indicators for Floquet Crystals
Jiabin Yu, Rui-Xing Zhang, Zhi-Da Song
Various exotic topological phases of Floquet systems have been shown to arise from crystalline symmetries. Yet, a general theory for Floquet topology that is applicable to all crys…
