Data and scripts from: Point-to-set lengths, local structure, and glassiness
The data files in this collection are associated with the paper "Point-to-set lengths, local structure, and glassiness", S. Yaida, P. Charbonneau, L. Berthier, and G. Tarjus, Phys. Rev. E, 2016. They include .dat, .eps and .m files with associated raw data and generating scripts to allow for replication of the figures. The growing sluggishness of glass-forming liquids is thought to be accompanied by growing structural order. The nature of such order, however, remains hotly debated. A decade ago, point-to-set (PTS) correlation lengths were proposed as measures of amorphous order in glass formers, but recent results raise doubts as to their generality. Here, we extend the definition of PTS correlations in order to agnostically capture any type of growing order in liquids, be it local or amorphous. This advance enables the formulation of a clear distinction between slowing down due to conventional critical ordering from that due to glassiness and provides a unified framework to assess the relative importance of specific local order and generic amorphous order in glass formation.
