Moiré and flat band physics
Isolated flat bands are the best place to study the interplay between quantum geometry and correlated phases, and moiré systems are the best platform to engineer those flat bands.

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.
