Abstract
Results are given from a density-matrix renormalization-group study of pairing on a striped $t\text{\ensuremath{-}}{t}^{\ensuremath{'}}\text{\ensuremath{-}}J$ lattice in the presence of boundary magnetic and pair fields. We find that pairing on a stripe depends sensitively on both $J/t$ and ${t}^{\ensuremath{'}}/t$. In the strong-pairing model-parameter regime, the stripes are easily coupled by the pair field and have a uniform phase. There is a small but measurable energy cost to create antiphase superconducting domain walls.
