• A dx2−y2-density wave (ddw) order of electron in two-dimensional t–J model is analyzed in saddle point level using the U(1) slave boson formalism. We considered not only the staggered flux (s-flux) order of spinon but also the s-flux order of holon. This analysis provides the relation between the s-flux order of spinon and the ddw order of electron. We discovered a new phase in the phase diagram. In this phase, there is a s-flux order of spinon, but no ddw order of electron. Our results are that (1) a region of electron ddw exists, (2) there is no coexistence of ddw and dx2−y2-wave pairing (singlet-RVB) in all region of phase diagram, and that (3) the ground state is a purely dx2−y2-wave superconducting state.
