Vertical and diagonal stripes in the extended Hubbard model

We extend previous real-space Hartree-Fock studies of static stripe stability to determine the phase diagram of the Hubbard model with anisotropic nearest-neighbor hopping t, by varying the on-site Coulomb repulsion U and investigating locally stable structures for representative hole doping levels x = 1/8 and x = 1/6. We also report the changes in stability of these stripes in the extended Hubbard model due to next-neighbor hopping t′ and to a nearest-neighbor Coulomb interaction V.
