Abstract

We investigate light-driven inversion of orbital selectivity in a two-orbital Hubbard-Kanamori model initially in an orbital-selective Mott phase. Using the matrix-product-state we show that tailored pulse excitations drive interorbital charge transfer that nearly reverses the orbital occupations. Single-particle spectral snapshots exhibit changes consistent with an interchange of the localized and itinerant characters of the orbitals. We analyze the relevant one- and two-photon excitation channels and show that chirping around the lower-frequency resonance enhances the transfer. These results establish a microscopic route to reversing orbital selectivity and accessing long-lived nonequilibrium states in multiorbital systems.
