Fig. 3: Quasiparticle properties of s-wave and d-wave pairing states.
From: Universal scaling behavior of resistivity under two-dimensional superconducting phase fluctuations
Momentum-dependent spectral function at T = 0.11 and ω = 0.1 is shown for a s-wave and b d-wave. c, d show the momentum dependence of the imaginary self-energy for the corresponding pairing symmetries under the same parameters as (a) and (b). The spectral function and self-energy are calculated by averaging over 72 samples with L = 70 and the energy broadening η = 0.008. e, f depict the average scattering rate around (π, 0) in the anti-nodal direction of the Brillouin zone and its symmetry-equivalent points obtained by 90∘ rotation around the (π, π) point, where strongest scattering occurs. The solid lines are fitting curves using the formula \(1/\tau \sim \exp (-B/\sqrt{T/{T}_{c}-1})\).
