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.
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.
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.
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.
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
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.


Comparative simulation study of colloidal gels and glasses.
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.
Dynamics of supercooled liquids and the glass transition
Closed nonlinear equations are derived for a self-consistent treatment of density propagation, self-diffusion and current relaxation in a classical monatomic fluid. The solution for a hard-sphere
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
REVIEW ARTICLE: Recent tests of the mode-coupling theory for glassy dynamics
An overview is given of recent tests of the mode-coupling theory for the evolution of structural relaxation in glass-forming liquids. Emphasis is put on comparisons between the leading-order
Dynamic light scattering study of concentrated microgel solutions as mesoscopic model of the glass transition in quasiatomic fluids
This paper presents a light scattering study of the dynamics of concentrated solutions of nearly monodisperse (σ≊0.16) spherical micronetwork particles consisting of highly cross‐linked polystyrene
Three-dimensional direct imaging of structural relaxation near the colloidal glass transition
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.
Higher-order glass-transition singularities in colloidal systems with attractive interactions.
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.

It is argued that the solid-solid phase transition should be experimentally observable in mixtures of uncharged colloids and non-adsorbing polymers.
Direct measurement of depletion potentials in mixtures of colloids and nonionic polymers
In colloidal suspensions containing a binary mixture of hard spheres depletion forces occur which substantially contribute to the interaction of the larger spheres among themselves and a wall,
