This review collects and describes experiments that employ colloidal suspensions to probe
physics in ordered and disordered solids and related complex fluids. The unifying feature of …

In this study, we present a detailed investigation of the morphology of binary colloidal
structures formed by self-assembly at air/water interface of particles of two different sizes …

Two-dimensional (2D) amorphous binary colloidal assemblies composed of particles of two
different sizes are characterized by the loss of hexagonal close-packing for larger particles …

We construct structural order parameters based on local angular and radial distribution
functions in dense colloidal suspensions. All the order parameters show significant …

Colloidal systems are an excellent example of a materials class for which interrogating
fundamental questions leads to answers of direct applied relevance. In our group, we in …

We report the development and application of a method for carrying out computational
investigations of the effects of mass and force-constant (FC) disorder on phonon spectra …

We derive exact results for correlations in the displacement fields {δ r}≡{δ r μ= x, y} in near-
crystalline athermal systems in two dimensions. We analyze the displacement correlations …

We study jammed near-crystalline materials composed of frictionless spheres in three
dimensions. We analyse the fluctuations in positions and forces produced by small …

The anomalous thermodynamic properties of glasses remain incompletely understood,
notably the anomalous peak in the heat capacity at low temperatures; it is believed to be due …

We investigate the vibrational modes of quasi-two-dimensional disordered colloidal
packings of hard colloidal spheres with short-range attractions as a function of packing …
