Abstract

By applying a variational Monte Carlo method to the two-dimensional t-J model, a couple of properties of striped states are studied. In the charge domain walls vertical (or horizontal) to the lattice (VDW), the hole density pe is favorable in energy similarly for 0.5 ≲ ρ_l ≲ 1, whereas in the diagonal domain walls (DDW) the stable hole density is limited to ρ_l = 1. Negative next-nearest-neighbor transfer (t′/t < 0) further stabilizes VDW with ρ_l = 0.5 and DDW with ρ_l = 1 against the d_x2-y2-wave superconducting state.
