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 p…

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…

Direct magnetic imaging of fractional Chern insulators in twisted MoTe with a superconducting sensor
Evgeny Redekop, Canxun Zhang, Heonjoon Park +10
In the absence of time reversal symmetry, orbital magnetization provides a sensitive probe of topology and interactions, with particularly rich phenomenology in Chern insulators wh…
