Imaging Interacting Two-Dimensional Anisotropic Electrons
Ziyu Xiang, Jianghan Xiao, Hongyuan Li +9
We directly visualize a two-dimensional anisotropic Wigner crystal and its quantum melting in monolayer 1T-ReSe2 using non-invasive scanning tunnelling microscopy. In crystals with…
Self-doped Crystal from Preempted Band-inversion Transitions
Jiechao Feng, Zhaoyu Han, Michael P. Zaletel +1
Recent experiments in rhombohedral graphene find evidence for a "self-doped" Wigner crystal (SDC) in which a slightly incommensurate Wigner crystal (WC) coexists with a small Fermi…
Imaging Electron-Hole Asymmetry in the Quantum Melting of Generalized Wigner Crystals
Emma Berger, Michael Arumainayagam, Zhihuan Dong +12
Two-dimensional moiré materials provide a versatile platform to explore phase transitions in strongly correlated systems. Using scanning tunneling microscopy (STM) we have imaged t…
Anyon superfluidity of excitons in quantum Hall bilayers
Zhaoyu Han, Taige Wang, Zhihuan Dong +2
The charged anyons of a fractional quantum Hall fluid are necessarily dispersionless due to the continuous magnetic translation symmetry. Neutral anyons, however, can disperse, res…
Extended quantum anomalous Hall effect in moiré structures: phase transitions and transport
Adarsh S. Patri, Zhihuan Dong, T. Senthil
Recent experiments on multilayer rhombohedral graphene have unearthed a number of interesting phenomena in the regime where Integer and Fractional Quantum Anomalous Hall phenomena…
Stability of Anomalous Hall Crystals in multilayer rhombohedral graphene
Zhihuan Dong, Adarsh S. Patri, T. Senthil
Recent experiments showing an integer quantum anomalous Hall effect in pentalayer rhombohedral graphene have been interpreted in terms of a valley-polarized interaction-induced Che…
Excitonic quantum criticality: from bilayer graphene to narrow Chern bands
Zhengyan Darius Shi, Hart Goldman, Zhihuan Dong +1
We study a family of excitonic quantum phase transitions describing the evolution of a bilayer metallic state to an inter-layer coherent state where excitons condense. We argue tha…
Theory of quantum anomalous Hall phases in pentalayer rhombohedral graphene moiré structures
Zhihuan Dong, Adarsh S. Patri, T. Senthil
Remarkable recent experiments on the moiré structure formed by pentalayer rhombohedral graphene aligned with a hexagonal Boron-Nitride substrate report the discovery of a zero fiel…
