Equilibrium cluster phases and low-density arrested disordered states: The role of short-range attraction and long-range repulsion
Francesco Sciortino, Stefano Mossa, Emanuela Zaccarelli +1
We study a model in which particles interact with short-ranged attractive and long-ranged repulsive interactions, in an attempt to model the equilibrium cluster phase recently disc…
Aging in short-ranged attractive colloids: A numerical study
G. Foffi, E. Zaccarelli, S. Buldyrev +2
We 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, of t…
Liquid stability in a model for ortho-terphenyl
E. La Nave, S. Mossa, F. Sciortino +1
We report an extensive study of the phase diagram of a simple model for ortho-terphenyl, focusing on the limits of stability of the liquid state. Reported data extend previous stud…
Short-ranged attractive colloids: What is the gel state ?
E. Zaccarelli, F. Sciortino, S. V. Buldyrev +1
We evaluate thermodynamic, geometric and dynamic properties of a short-ranged square well binary mixture to provide a coherent picture of this simple, but rich, model for colloidal…
Physics of the liquid-liquid critical point
Francesco Sciortino, Emilia La Nave, Piero Tartaglia
Within the inherent structure (IS) thermodynamic formalism introduced by Stillinger and Weber [F. H. Stillinger and T. A. Weber, Phys. Rev. A {\bf 25}, 978 (1982)] we address the b…
Structural arrest in dense star polymer solutions
G. Foffi, F. Sciortino, P. Tartaglia +5
The dynamics of star polymers has been investigated via extensive Molecular- and Brownian Dynamics simulations for a large range of functionality and packing fraction . The…
Evidence of a higher-order singularity in dense short-ranged attractive colloids
Francesco Sciortino, Piero Tartaglia, Emanuela Zaccarelli
We study a model in which particles interact through a hard-core repulsion complemented by a short-ranged attractive potential, of the kind found in colloidal suspensions. Combinin…
Activated bond-breaking processes preempt the observation of a sharp glass-glass transition in dense short-ranged attractive colloids
Emanuela Zaccarelli, Giuseppe Foffi, Francesco Sciortino +1
We study -- using molecular dynamics simulations -- the temperature dependence of the dynamics in a dense short-ranged attractive colloidal glass to find evidence of the kinetic gl…
A test of non-equilibrium thermodynamics in glassy systems: the soft-sphere case
E. La Nave, F. Sciortino, P. Tartaglia +2
The scaling properties of the soft-sphere potential allow the derivation of an exact expression for the pressure of a frozen liquid, i.e., the pressure corresponding to configurati…
Fluctuation-dissipation relations and energy landscape in an out-of-equilibrium strong glass-forming liquid
Antonio Scala, Chantal Valeriani, Francesco Sciortino +1
We study the out-of-equilibrium dynamics following a temperature-jump in a model for a strong liquid, BKS-silica, and compare it with the well known case of fragile liquids. We cal…
