Fractional Chern insulator on a triangular lattice of strongly correlated $t_{2g}$ electrons

Stefanos Kourtis, Jörn W. F. Venderbos, Maria Daghofer

We discuss the low-energy limit of three-orbital Kondo-lattice and Hubbard models describing $t_{2g}$ orbitals on a triangular lattice near half-filling. We analyze how very flat b…
