Bound and unbound trions are included via four-point correlation functions representing electron–hole pair transitions in the presence of carrier populations. The spectra calculated for semiconductor nanorings show bleaching of the exciton resonance and induced absorption at energies corresponding to transitions to bound and unbound trion states. Without a magnetic field, induced absorption below the exciton line due to bound negatively (positively) charged trions appears when the two electrons (holes) of the trion are in different bands. A magnetic field introduces characteristic modifications of the spectra that can be attributed to the Aharonov–Bohm effect.
