Exact diagonalization results for resonant inelastic x-ray scattering spectra of one-dimensional Mott insulators
Stefanos Kourtis, Jeroen van den Brink, Maria Daghofer
We examine the momentum-dependent excitation spectra of indirect as well as direct resonant inelastic x-ray scattering (RIXS) processes in half-filled (extended) Hubbard rings. We…

Fractional quantum-Hall liquid spontaneously generated by strongly correlated t_2g electrons
Jörn W. F. Venderbos, Stefanos Kourtis, Jeroen van den Brink +1
For topologically nontrivial and very narrow bands, Coulomb repulsion between electrons has been predicted to give rise to a spontaneous fractional quantum-Hall (FQH) state in abse…
