Among the broad spectrum of systems predicted to exhibit topologicalsuperconductivity and Majorana fermions, one-dimensional wires with strongspin-orbit coupling provide one of the most promising experimental candidates.Here we investigate the fate of the topological superconducting phase in suchwires when repulsive interactions are present. Using a combination of DensityMatrix Renormalization Group, bosonization, and Hartree-Fock techniques, wedemonstrate that while interactions degrade the bulk gap -consistent withrecent results of Gangadharaiah et al.- they also greatly expand the parameterrange over which the topological phase arises. In particular, we show that withinteractions this phase can be accessed over a broader chemical potentialwindow, thereby leading to greater immunity against disorder-induced chemicalpotential fluctuations in the wire. We also suggest that in certain wiresstrong interactions may allow Majorana fermions to be generated withoutrequiring a magnetic field.
