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

Here, we capitalize on this opportunity by directly measuring the response of a liquid to 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, which evolves sensitively with the applied field period, as locally favored structures of the unperturbed liquid are selectively enhanced. These results open new research directions: by imposing artificial density modulations it is possible to extract structural information that are inaccessible to scattering experiments.
