Molecular wires of the acene-family can be viewed as a physical realizationof a two-rung ladder Hamiltonian. For acene-ladders, closed-shell ab-initiocalculations and elementary zone-folding arguments predict incommensurate gaposcillations as a function of the number of repetitive ring units,$N_{\text{R}}$, exhibiting a period of about ten rings. %% Results employingopen-shell calculations and a mean-field treatment of interactions suggestanti-ferromagnetic correlations that could potentially open a large gap andwash out the gap oscillations. % Within the framework of a Hubbard model withrepulsive on-site interaction, $U$, we employ a Hartree-Fock analysis and thedensity matrix renormalization group to investigate the interplay of gaposcillations and interactions. % We confirm the persistence of incommensurateoscillations in acene-type ladder systems for a significant fraction ofparameter space spanned by $U$ and $N_{\text{R}}$.
