Superconducting correlations ∣Φyy(r)∣ on three-leg cylinder at doping level a δ = 1/9 and b δ = 1/12, where dashed lines denote fittings to an exponential function \(f(r) \sim {{\rm{e}}}^{-r/{\xi }_{{\rm{sc}}}}\). Insets are the ratio Φxy(r)/Φyy(r) < 0, where the out of phase indicates d-wave type pairing. c The normalized function ϕyy(r) = Φyy(r)/f(r) at δ = 1/9 and δ = 1/12, which directly reflects the spatial oscillation of Φyy(r). d Fourier transformation ϕyy(q) of ϕyy(r) at δ = 1/12 and δ = 1/9, where peaks lie at Q = 3πδ/2a0 giving the total momentum of the pairing. Note that filled (open) symbols denote positive (negative) value.
