versus width σ for a gaussian PDF resulting from numerical simulations of the full model (grey points) and the phenomenological model (curves).

We set N = 1000. For each value of σ, averages were performed over 4 × 103 different realizations of disorder. The numerical points (in grey) are shown with the associated error bars (calculated as the mean absolute deviations). The curves correspond to the outcomes of the phenomenological model with the atom-localized-mode coupling strength calculated as 
(red-dotted) and 
(green-dotdashed). Inset: behavior of 
for low values of σ.
