      abstract     = {We investigate the localization of low-energy single
                      quasi-particle states in the 7/9-hybrid nanoribbon system in
                      the presence of strong interactions and within a finite
                      volume. We consider two scenarios, the first being the
                      Hubbard model at half-filling and perform quantum Monte
                      Carlo simulations for a range $U$ that includes the strongly
                      correlated regime. In the second case we add a
                      nearest-neighbor superconducting pairing $\Delta$ and take
                      the symmetric line limit, where $\Delta$ is equal in
                      magnitude to the hopping parameter $t$. In this limit the
                      quasi-particle spectrum and wavefunctions can be directly
                      solved for general onsite interaction $U$. In both cases we
                      extract the site-dependent quasi-particle wavefunction
                      densities and demonstrate that localization persists in
                      these non-perturbative regimes under particular scenarios.},
