Hole-pair symmetry and excitations in the strong-coupling extended t-Jz model: competition between d-wave and p-wave

R. M. Fye, G. B. Martins, E. Dagotto

We analytically calculate the ground state pairing symmetry and excitation spectra of two holes doped into the half-filled t-t'-t"-Jz model in the strong-coupling limit (Jz>>|t|,|t…
