Broad regions of horizontal and vertical spin stripes appear at low temperature in the Hubbard model, with wavelengths that vary nonlinearly with hole doping and are highly sensitive to the ratio of nearest- and next-nearest-neighbor hoppings.

Spin-stripes in the Hubbard model: a combined DMFT and Bethe-Salpeter analysis
Broad regions of horizontal and vertical spin stripes appear at low temperature in the Hubbard model, with wavelengths that vary nonlinearly with hole doping and are highly sensitive to the ratio of nearest- and next-nearest-neighbor hoppings.
