Abstract

Significance The origin of dynamical slowing down toward glass transition is a fundamental unsolved problem in condensed matter physics. A crucial question is whether this slowing down has a structural origin. Recently, a method to detect hidden order within the fluid was proposed, based on the idea that freezing a fraction of the particles in a system causes a transition akin to glass transition. Here, we show that a glass former, polydisperse hard disks, has a strong increase of structural order, well correlated with slow dynamics, which goes undetected by the pinning method. This casts doubt on the order-agnostic qualities of the pinning length scale and keeps static length scales in the race for plausible explanations of the glass transition problem.
