Many-body ground states from decomposition of ideal higher Chern bands: Applications to chirally twisted graphene multilayers

Motivated by the higher Chern bands of twisted graphene multilayers, we consider flat bands with arbitrary Chern number C with ideal quantum geometry. While C>1 bands differ from Landau levels, we show that these bands host exact fractional Chern insulator (FCI) ground states for short-range inte...
