Experiments, theory, and simulation were used to study glass formation in a simple model system composed of hard spheres with short-range attraction (“sticky hard spheres”). The experiments, using well-characterized colloids, revealed a reentrant glass transition line. Mode-coupling theory calculations and molecular dynamics simulations suggest that the reentrance is due to the existence of two qualitatively different glassy states: one dominated by repulsion (with structural arrest due to… 
Glasses in hard spheres with short-range attraction.
TLDR
Dynamic light scattering results, which cover 11 orders of magnitude in time, are consistent with the existence of two distinct kinds of glasses, those dominated by interparticle repulsion and caging, and thosedominated by attraction.
Aging in short-ranged attractive colloids: a numerical study.
TLDR
The aging dynamics in a model for dense simple liquids, in which particles interact through a hard-core repulsion complemented by a short-ranged attractive potential, shows novel unexpected features.
Structural and dynamical features of multiple metastable glassy states in a colloidal system with competing interactions.
TLDR
It is suggested that a balance between repulsions and attractions controls the nature of dynamic arrest of glassy states in a colloidal system with long-ranged electrostatic repulsion and short-ranged depletion attractions.
Mesoscopic lattice Boltzmann modeling of soft-glassy systems: Theory and simulations
A multicomponent lattice Boltzmann model recently introduced [R. Benzi et al., Phys. Rev. Lett. 102, 026002 (2009)] to describe some dynamical behaviors of soft-flowing materials is theoretically
Glasses in colloid-polymer mixtures
This work consists of detailed experimental studies of the structure and dynamics of glassy states in hard spheres with short-range attraction. The well-characterized model system is a suspension of
Numerical study of the glass–glass transition in short-ranged attractive colloids
We report extensive numerical simulations in the glass region for a simple model of short-ranged attractive colloids, the square well model. We investigate the behaviour of the density
Gel to glass transition in simulation of a valence-limited colloidal system.
TLDR
By studying a large region of T and packing fraction phi, this work is able to estimate both the location of the liquid-gas phase separation spinodal and the locus of dynamic arrest, where the system is trapped in a disordered nonergodic state.
The Glass-to-Glass Transition and Its End Point in a Copolymer Micellar System
TLDR
Experimental evidence, obtained from small-angle neutron scattering and photon correlation measurements, indicating the existence of two types of structurally arrested states in a copolymer micellar system with a short-range interparticle attractive interaction, and an end point of this transition line beyond which the two glasses become identical in their local structure and their long-time dynamics are found.

TLDR
Using computer simulations, the mechanisms causing aggregation and structural arrest of colloidal suspensions interacting with a short-ranged attraction at moderate and high densities are identified and correctly predicted by mode coupling theory.
Kinetic glass transition in a micellar system with short-range attractive interaction
We show that percolation and structural arrest transitions coexist in different regions of the phase diagram of a copolymer-micellar system and relate them to short-range intermicellar attraction.

Three-dimensional direct imaging of structural relaxation near the colloidal glass transition
TLDR
Confocal microscopy was used to directly observe three-dimensional dynamics of particles in colloidal supercooled fluids and colloidal glasses; connected clusters of these mobile particles could be identified; and the cluster size distribution, structure, and dynamics were investigated.

TLDR
The transition from a liquid to a glass in colloidal suspensions of particles interacting through a hard core plus an attractive square-well potential is studied within the mode-coupling-theory framework and shows stretching of huge dynamical windows, in particular logarithmic time dependence.

TLDR
It is argued that the solid-solid phase transition should be experimentally observable in mixtures of uncharged colloids and non-adsorbing polymers.
