22. Note that due to the finite resolution in momentum space, the DCA underestimates low-energy spectral weight in superconductors where the gap has nodes on the Fermi surface. As a result we find a fully developed gap at low temperatures instead of a density of states that vanishes linearly in frequency as expected for a d-wave superconductor.
