Ferromagnetism and Topology of the Higher Flat Band in a Fractional Chern Insulator
Heonjoon Park, Jiaqi Cai, Eric Anderson +18
The recent observation of the fractional quantum anomalous Hall effect in moiré fractional Chern insulators provides an opportunity to investigate zero magnetic field anyons. To po…
Visualizing the microscopic origins of topology in twisted molybdenum ditelluride
Ellis Thompson, Keng Tou Chu, Florie Mesple +14
In moiré materials with flat electronic bands and suitable quantum geometry, strong correlations can give rise to novel topological states of matter. The nontrivial band topology o…
Gauge theory of giant phonon magnetic moment in doped Dirac semimetals
Wenqin Chen, Xiao-Wei Zhang, Ying Su +3
We present a quantum theory of phonon magnetic moment in doped Dirac semimetals. Our theory is based on an emergent gauge field approach to the electron-phonon coupling, applicable…
Higher Landau-Level Analogs and Signatures of Non-Abelian States in Twisted Bilayer MoTe
Chong Wang, Xiao-Wei Zhang, Xiaoyu Liu +3
Recent experimental discovery of fractional Chern insulators at zero magnetic field in moiré superlattices has sparked intense interests in bringing Landau level physics to flat Ch…
