Magnon-induced hybridization brightens excitons in ferromagnetic semiconductors
Man-Yat Chu, Mona Berciu
Excitons in magnetic semiconductors have energies and spin structures that are sensitive to the underlying magnetic order. We study this coupling in a minimal one-dimensional latti…

Sharp transitions in the spectra of small Frenkel-like excitons for multi-orbital lattice systems
Man-Yat Chu, Mona Berciu
We propose a method for calculating exciton spectra and wavefunctions for model lattice Hamiltonians, based on real-space electron-hole propagators. We verify that our results agre…
