I will present results on using a lattice tight-binding Bogoliubov-de Gennes formulation of nonuniform superconducting systems and solving self-consistently for the superconducting order parameter. Systems studied include Josephson junctions in graphene and spin-orbit coupled semiconductors, superconducting vortices in spin-orbit coupled semiconductors, and studies of the local effect of impurities and disordered edges in unconventional superconductors. While the method has limitations, especially with regards to system sizes possible to study, it offers a microscopically accurate description of the superconducting state, which can be crucial for a correct physical description of nonuniform superconducting systems.
