We present a theoretical and numerical investigation of correlated multi-electron states of
hexagonal semiconductor rings. Both single-particle and correlated states show localization
patterns in the six corners and energy spectra degeneracies corresponding to a hexagonal benzene
ring. Thus, our results can aid the interpretation of energy-loss or near-field experiments that, in
turn, shed light on the nature of molecular few-particle orbitals of artificial benzene. Surprisingly,
we find that charges get more localized in the corners as the number of electrons increases, up to
six, this indicating the deficiency of a picture based on orbitals delocalized on the whole ring. We
also expose the presence of several spin-correlated states and the effect of an asymmetry of the
system [-]
