    • In Ref. 17 a similar smooth landscape was considered as due to out-of-plane quenched disorder. The consequences in the LDOS of the enhanced forward scattering were investigated, and the occurrence of a broad peak at small momenta was found in agreement with our findings (see Sec. III A).

    • Although the doping inhomogeneities entail a distribution of the chemical potential, this has minor effects on the zeroth-order local DOS. In particular, assuming a linear band dispersion around the nodes, as in the following simplified approach, the variations of the chemical potential do not affect the linear energy dependence of the DOS.

    • To render the following expressions simpler we neglected the periodic character of the momentum dependence, but we explicitly considered it in the actual numerical calculations.
