A thermodynamic description of colloidal glasses    [PDF]

Mauro Sellitto, Francesco Zamponi
The phase behavior of hard-sphere particles interacting with a short-ranged potential is studied in the limit of infinite space dimensionality via the Franz-Parisi approach and the replica method of disordered systems. For an attractive square-well potential the phase diagram exhibits reentrancy of the liquid-glass transition, multiple glass states and glass-glass transition. For a repulsive square shoulder potential no such special features are observed. Our results show that the Franz-Parisi approach can be consistently extended to higher-order glass singularities and that interparticle attraction is crucial for complex glassy behavior in infinite dimensions, at least for monodisperse systems.
