abstract: 'We report a detailed experimental study of the structure and dynamics of glassy states in hard spheres with short-range attraction. The system is a suspension of nearly-hard-sphere colloidal particles and non-adsorbing linear polymer which induces a depletion attraction between the particles. Observation of crystallization reveals a re-entrant glass transition. Static light scattering shows a continuous change in the static structure factors upon increasing 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 inter-particle repulsion and caging, and those dominated by attraction. Samples close to the ‘A3 point’ predicted by mode coupling theory for such systems show very slow, logarithmic dynamics.'

Introduction {#s:Intro}
============

Glassy states are found in many systems [@glassReview1]. However, understanding the glass transition is still a major challenge for statistical and condensed-matter physics. Simple and well-characterized models hold an important place in this field. The glass transition in the simplest model colloid, a suspension of hard spheres, has been studied in detail for more than
