Fractional Chern insulators with strong interactions far exceeding bandgaps
Stefanos Kourtis, Titus Neupert, Claudio Chamon +1
We study two models for spinless fermions featuring topologically non-trivial bands characterized by Chern numbers at fractional filling. Using exact diagonalization, we s…
Femtosecond dynamics of magnetic excitations from resonant inelastic x-ray scattering in CaCu2O3
Valentina Bisogni, Stefanos Kourtis, Claude Monney +10
Taking spinon excitations in the quantum antiferromagnet CaCu2O3 as an example, we demonstrate that femtosecond dynamics of magnetic excitations can be probed by direct resonant in…
Combined topological and Landau order from strong correlations in Chern bands
Stefanos Kourtis, Maria Daghofer
We present a class of states with both topological and conventional Landau order that arise out of strongly interacting spinless fermions in fractionally filled and topologically n…
