Using video microscopy, we measure local spatial constraints in disordered binary colloidal samples, ranging from dilute fluids to jammed glasses, and probe their spatial and temporal correlations to local dynamics during the glass transition. We observe the emergence of significant correlations between constraints and local dynamics within the Lindemann criterion, which coincides with the onset of glassy dynamics in supercooled liquids. Rigid domains in fluids are identified based on local…

It is found that spring stiffness involving small particles also varies non-monotonically with increasing attraction strength, while stiffness between large particles increases monotonically, consistent with thenon-monotonic long-time structural relaxation dynamics of the re-entrant glass.

It is revealed that it is the percolation of the force-bearing network that allows long-range stress transmission even under such circumstance, and the emergent solidity of amorphous materials is a consequence of nontrivial self-organisation of the disordered mechanical architecture.

In marginally jammed solids confined by walls, we calculate the particle and ensemble averaged value of an order parameter, 〈Ψ(r)〉, as a function of the distance to the wall, r. Being a microscopic…

A continuous family of elastic propagators is unveiled, which are identical for the soft modes and for the equilibrium configurations, and interpolates between the standard quadrupolar propagator and the fracture-like one as the anisotropy of the elastic medium is increased.

This work challenges the former single-scale view of the rigidity percolation and derives a generalized hyperscaling relation in the framework of the two-scale scenario, suggesting that the jamming transition of systems with short-range attractions is still continuous.

It is shown how large fluctuations stabilize bcc crystals formed from charged colloids, giving rise to strongly power-law correlated heterogeneous dynamics, and it is found that significant nonaffine particle displacements lead to a vanishing of the nonAffine shear modulus at the transition.
