Stripe Phases in the Hubbard Model

We investigate the magnetic and charge ordering in the stripe phases obtained while using correlated wave functions for finite 8×8 clusters described by the Hubbard model with extended hopping. Nonmagnetic vertical (01) site-centered domain walls and (11) bond-centered stripes are found for the parameters of La$\text{}_{2-x}$Sr$\text{}_{x}$CuO$\text{}_{4}$ and YBa$\text{}_{2}$Cu$\text{}_{3}$O$\text{}_{6+x}$, respectively, at doping δ=1/8. The obtained half-filled domain nonmagnetic walls reproduce the maxima observed in neutron scattering for La$\text{}_{2-x}$Sr$\text{}_{x}$CuO$\text{}_{4}$.
