Inter-layer modified -wave superconductivity in an effectively doped spin-1 ladder
We construct a four-leg spin-1/2 t – J type model to simulate a doped two-leg spin-1 antiferromagnetic Heisenberg ladder. Employing renormalized mean-field theory with simple Gutzwiller factors, we obtain three degenerate superconducting states with different pairing symmetry. Through improving the...
