Skyrmion Fractional Chern Insulator: An Intrinsically Multiband Route to Fractionalization in Rhombohedral Graphene
Julian May-Mann, Tixuan Tan, Patrick J. Ledwith +2
We propose an unconventional microscopic origin for the fractional quantum anomalous Hall (FQAH) effect in rhombohedral graphene moiré superlattices: skyrmion fractionalization. We…
Visualizing orbital magnetism in electron doped rhombohedral multilayer graphene
Owen I. Sheekey, Trevor B. Arp, Benjamin A. Foutty +24
Electron doped rhombohedral multilayer graphene at high displacement field features an exceptionally flat band minimum with near-ideal quantum geometry. Experiments in this regime…
The ideal limit of rhombohedral graphene: Dynamical skyrmion lattices and their excitations
Tixuan Tan, Patrick J. Ledwith, Trithep Devakul
We introduce an interacting ideal limit of rhombohedral graphene in which interactions spontaneously generate a correlated Chern insulator. Our analysis reveals that this Chern ins…
Nonvolatile Switching of Magnetism via Gate-Induced Sliding in Tetralayer Graphene
Daniel Brandon, Tixuan Tan, Yiwen Ai +7
Interlayer sliding degrees of freedom often determine the physical properties of two-dimensional (2D) materials. In graphene, for instance, the metastable rhombohedral stacking arr…
Fractional Chern mosaic in supermoiré graphene
Yves H. Kwan, Tixuan Tan, Trithep Devakul
We propose the realization of a fractional Chern mosaic: a state characterized by a spatially varying topological order. This state is enabled by a separation of length scales that…
Wavefunction approach to the fractional anomalous Hall crystal
Tixuan Tan, Julian May-Mann, Trithep Devakul
We propose fractional anomalous Hall crystals (FAHCs) as possible ground states of strongly interacting electrons in parent bands with Berry curvature. FAHCs are exotic states of m…
Importance of electron-phonon coupling near the electron-liquid to Wigner-crystal transition in two-dimensional atomically thin materials
Tixuan Tan, Vladimir Calvera, Steven A. Kivelson
We study the effect of electron-phonon coupling on the location of the Fermi Liquid to Wigner Crystal transition in the two-dimensional electron gas realized in various material pl…
Parent Berry curvature and the ideal anomalous Hall crystal
Tixuan Tan, Trithep Devakul
We study a model of electrons moving in a parent band of uniform Berry curvature. At sufficiently high parent Berry curvature, we show that strong repulsive interactions genericall…
Designing topology and fractionalization in narrow gap semiconductor films via electrostatic engineering
Tixuan Tan, Aidan P. Reddy, Liang Fu +1
We show that topological flat minibands can be engineered in a class of narrow gap semiconductor films using only an external electrostatic superlattice potential. We demonstrate t…
