Hello all,
I’d like to ask about the convergence of the scattering rates wrt # q points and broadening parameter (\eta).
From Fig. S2(a) of Ponce et al., Phys. Rev. B 97, 121201(R) (2018), I understand that the scattering rates (where the mobility is plotted) will diverge as the \eta approaches zero (I suppose for each data point in that figure, the # q points is large enough). On contrary, according to Zhou et al., PRB 94, 201201(R) (2016), by decreasing the \eta and increasing the # q points, the scattering rates will eventually become converged, i.e., the \eta->0 limit exists.
I fee like these two arguments are very different. Could you please help me clarify? Thanks.
