Topological Heavy Fermion Principle For Flat (Narrow) Bands With Concentrated Quantum Geometry
Jonah Herzog-Arbeitman, Jiabin Yu, Dumitru CÄlugÄru +8
We propose a general principle for the low-energy theory of narrow bands with concentrated Berry curvature and Fubini-Study metric in the form of a map to Anderson-"+" models compo…
