Engineering geometrically flat Chern bands with Fubini-Study Kähler structure

Engineering geometrically flat Chern bands with Fubini-Study Kähler structure

We describe a systematic method to construct models of Chern insulators whose Berry curvature and the quantum volume form coincide and are flat over the Brillouin zone; such models are known to be suitable for hosting fractional Chern insulators. The bands of Chern insulator models where the Berry curvature and …
