Band topology and quantum geometry in moiré flat bands
Moiré systems provide the best platform to engineer isolated flat bands, enabling the studies on the interplay between band topology, quantum geometry, and correlation.

Band topology in projected spectrum
The band topology and quantum geometry derived from the eigenstates of the projected spectrum are as important as those derived from the energy eigenstates.
