Theory of Quantum Anomalous Hall Phases in Pentalayer Rhombohedral Graphene Moiré Structures
Published 2024“…Here we show that electron-electron interactions play a crucial role, and present microscopic theoretical calculations demonstrating the emergence of a nearly flat, isolated, Chern-1 band and FQAH phases in this system. We also study the four- and six-layer analogs and identify parameters where a nearly flat isolated Chern-1 band emerges which may be suitable to host FQAH physics.…”
