Dynamic relaxation is an intrinsic and universal feature of glasses and enables fluctuation
and dissipation to occur, which induces plentiful behaviour, maintains equilibrium, and …

As one increases the concentration of a colloidal suspension, the system exhibits a dramatic
increase in viscosity. Beyond a certain concentration, the system is said to be a colloidal …

The slow transition from an out-of-equilibrium glass towards a supercooled liquid is a
complex relaxation phenomenon. In this Letter, we study the correlation between …

Extensive molecular dynamics simulations are performed on a glass-forming Lennard-Jones
mixture to determine the nature of the cooperative motions occurring in this model fragile …

The arrangements of particles and forces in granular materials have a complex organization
on multiple spatial scales that range from local structures to mesoscale and system-wide …

We use multispeckle dynamic light scattering to measure the dynamic structure factor, f (q, τ),
of gels formed by aggregation of colloids. Although the gel is an elastic solid, f (q, τ) nearly …

We use x-ray photon correlation spectroscopy to investigate the structural relaxation process
in a metallic glass on the atomic length scale. We report evidence for a dynamical crossover …

We study theoretically the role of aging in the rheology of soft materials. We define several
generalized rheological response functions suited to aging samples (in which time …

The configurational entropy is one of the most important thermodynamic quantities
characterizing supercooled liquids approaching the glass transition. Despite decades of …

We use conventional and multispeckle dynamic light scattering to investigate the dynamics
of a wide variety of jammed soft materials, including colloidal gels, concentrated emulsions …
