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 …

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 …

Unusual features of the vibrational density of states D (ω) of glasses allow one to rationalize
their peculiar low-temperature properties. Simulational studies of D (ω) have been restricted …

Epithelial cell monolayers show remarkable displacement and velocity correlations over
distances of ten or more cell sizes that are reminiscent of supercooled liquids and active …

We use numerical simulations to study the dynamics of dense assemblies of self-propelled
particles in the limit of extremely large, but finite, persistence times. In this limit, the system …

Plastic deformation in amorphous solids is known to be carried by stress-induced localized
rearrangements of a few tens of particles, accompanied by the conversion of elastic energy …

We theoretically and numerically study the elastic properties of hard-sphere glasses and
provide a real-space description of their mechanical stability. In contrast to repulsive …

We characterize vibrational motion occurring at low temperatures in dense suspensions of
soft repulsive spheres over a broad range of volume fractions encompassing the jamming …

Collective motion of large human crowds often depends on their density. In extreme cases
like heavy metal concerts and black Friday sales events, motion is dominated by physical …

A theory for the microscopic structure and the vibrational properties of soft sphere glass at
finite temperature is presented. With an effective potential, derived here, the phase diagram …
