Abstract
We investigate a string-density wave state in the underdoped region of high-T{sub c} cuprates theoretically based on the two-dimensional Hubbard model. There is a tendency towards a formation of stripes in the low-doping region due to the lattice distortion and strong Coulomb interaction. The tilt of CuO octahedra induces transfer integrals between p{sub x,y}-orbitals and Cu t{sub 2g}-orbitals, which brings about the spin-orbit interaction for the d electrons in the CuO plane. The spin-orbit interaction induces a flux state with time-reversal symmetry breaking; then the striped state with a flux, which is a generalization of d-density wave, is stabilized from the under to lightly doped region. This state shows a pseudogap behavior due to a modification of the electron dispersion relation in the presence of flux. It is shown that the spin-orbit interaction stabilizes the diagonal-striped state in the lightly doped region.
