Figure:

Theoretical spectral intensity at T=0.06t and pth=0.05 (a) in the energy-momentum space and (b) in the first quadrant of the Brillouin zone at low energy (ω∼0). Black circles and white squares denote, respectively, the peak positions of quasiparticle and in-gap bands, which are separated by an s-wave pseudogap. The dotted blue curve plots the position of the maximal-scattering rate (i.e., the imaginary part of self-energy) at each momentum. The green (dark gray) arrow in (b) denotes the momentum cut used in (a). (c) Local DOS in a wide energy range displaying the Hubbard bands (ω<0 and ω∼6t). The shaded area denotes the low-energy region plotted in (a). (d) Temperature dependence of the scattering rate within the pseudogap at ω=0.36t (node) and 0.28t (antinode). (e)–(g) Spectral function along the cuts depicted in (b), comparable to available ARPES data [6]. The dashed line indicates the upper energy limit reached in Figs. 3(e)–3(g) of Ref. 6. (h) Tunneling conductance at T=0.06t, comparable to, e.g., Fig. 5(b) (inset) of Ref. 38.
