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…

Structural and short-time vibrational properties of colloidal glasses and supercooled liquids in the vicinity of the re-entrant glass transition.

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.

Emergent solidity of amorphous materials as a consequence of mechanical self-organisation

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.

Revealing key structural features hidden in liquids and glasses

A great success of solid state physics comes from the characterization of crystal structures in the reciprocal (wave vector) space. The power of structural characterization in Fourier space

Microscopic ergodicity breaking governs the emergence and evolution of elasticity in glass-forming nanoclay suspensions.

A study combining x-ray photon correlation spectroscopy (XPCS) with in situ rheology to investigate the microscopic dynamics and mechanical properties of aqueous suspensions of the synthetic hectorite clay Laponite, suggesting the soft solid forms through precursors of dynamically localized clusters.

Jamming in confined geometry: Criticality of the jamming transition and implications of structural relaxation in confined supercooled liquids

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 general structural order parameter for the amorphous solidification of a supercooled liquid.

The persistent problem posed by the glass transition is to develop a general atomic level description of amorphous solidification. The answer proposed in this paper is to measure a configuration's

Soft modes and strain redistribution in continuous models of amorphous plasticity: the Eshelby paradigm, and beyond?

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.

Percolation transitions in compressed SiO2 glasses

Amorphous–amorphous transformations under pressure are generally explained by changes in the local structure from low- to higher-fold coordinated polyhedra1–4. However, as the notion of scale

Two-Scale Scenario of Rigidity Percolation of Sticky Particles.

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.

Structures of Local Rearrangements in Soft Colloidal Glasses.

These experiments provide an efficient structural identifier for the fragile regions in glasses and highlight the important role of structural correlations in the physics of glasses.

Cage-jump motion reveals universal dynamics and non-universal structural features in glass forming liquids

The sluggish and heterogeneous dynamics of glass forming liquids is frequently associated to the transient coexistence of two phases of particles, respectively with a high and low mobility. In the

Cooperative rearrangement regions and dynamical heterogeneities in colloidal glasses with attractive versus repulsive interactions.

The experiments demonstrate explicitly that glassy dynamics can depend on the sign of the interparticle interaction, and the attractive glass dynamics is found to be heterogeneous over a wider range of time and length scales, and its CRRs involve more particles.

A Topographic View of Supercooled Liquids and Glass Formation

Various static and dynamic phenomena displayed by glass-forming liquids, particularly those near the so-called "fragile" limit, emerge as manifestations of the multidimensional complex topography of

Supercooled liquids and the glass transition

Current theoretical knowledge of the manner in which intermolecular forces give rise to complex behaviour in supercooled liquids and glasses is discussed.

Heterogeneous dynamics at the glass transition in van der Waals liquids, in the bulk and in thin films

Abstract:It has been shown over the last few years that the dynamics close to the glass transition is strongly heterogeneous, both by measuring the diffusion coefficient of tagged particles or by NMR

Unified Criterion for Temperature-Induced and Strain-Driven Glass Transitions in Metallic Glass.

A unified scenario, analogous to the well-known Lindemann criterion for crystal melting, provides insight into the structural origin of the strain-induced glass-liquid transition.

Critical-like behaviour of glass-forming liquids.

The glass transition may be a new type of critical phenomenon where a structural order parameter is directly linked to slowness, and a far more direct link than thought before between glass transition and critical phenomena is suggested.

Direct Observation of Entropic Stabilization of bcc Crystals Near Melting.

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.
