Raw data and software for 'Beyonfd linear response in colloids'

Colloidal suspensions offer huge potential to provide new insights into the fundamental behaviorof liquids both because the particles’ positions can be directly measured, and because their softnature provides the unique possibility to go beyond linear response by exposing the system tostrong fields. Here, we capitalize on this opportunity by directly measuring the response of a liquidto a strong spatially periodic external field in experiments, simulations and theoretical models.Strikingly, we observe a structural change in the direction perpendicular to the field variation, whichevolves sensitively with the applied field period, as locally favored structures of the unperturbedliquid are selectively enhanced. These results open new research directions: by imposing artificialdensity modulations it is possible to extract structural information that are inaccessible to scatteringexperiments.
