Abstract
We study competition between different phases in a strongly correlated nanostructure with an edge. Making use of the self-consistent Green's function and density matrix renormalization group methods, we study a system described by the and models on a strip of a square lattice with a linear hole density . At intermediate interaction strength we find edge stripelike states, reminiscent of the bulk stripes that occur at smaller . We find that stripes attach to edges more readily than hole pairs, and that the edge stripes can exhibit a peculiar phase separation.
