Phase coexistence of cluster crystals: Beyond the gibbs phase rule
(Physical Review Letters, 2007-12-07)
We report a study of the phase behavior of multiple-occupancy crystals through simulation. We argue that in order to reproduce the equilibrium behavior of such crystals, it is essential to treat the number of lattice sites ...
Phase behavior and far-from-equilibrium gelation in charged attractive colloids
(Physical Review E - Statistical, Nonlinear, and Soft Matter Physics, 2007-05-03)
In this Rapid Communication we demonstrate the applicability of an augmented Gibbs ensemble Monte Carlo approach for the phase behavior determination of model colloidal systems with short-ranged depletion attraction and ...
Gas-solid coexistence of adhesive spheres
(Journal of Chemical Physics, 2007-05-28)
In this note, the authors investigate whether the gas-liquid critical point can remain stable with respect to solidification for narrow attractive interactions down to the Baxter limit. Using a crude cell theory, the authors ...
Out-of-equilibrium dynamical fluctuations in glassy systems
(Journal of Chemical Physics, 2004-11-22)
In this paper we extend the earlier treatment of out-of-equilibrium mesoscopic fluctuations in glassy systems in several significant ways. First, via extensive simulations, we demonstrate that models of glassy behavior without ...
Dynamical heterogeneity and nonlinear susceptibility in supercooled liquids with short-range attraction
(Physical Review Letters, 2007-09-24)
Recent work has demonstrated the strong qualitative differences between the dynamics near a glass transition driven by short-ranged repulsion and one governed by short-ranged attraction. Here we study in detail the behavior ...
Systematic characterization of thermodynamic and dynamical phase behavior in systems with short-ranged attraction
(Physical Review E - Statistical, Nonlinear, and Soft Matter Physics, 2007-02-02)
In this paper we demonstrate the feasibility and utility of an augmented version of the Gibbs ensemble Monte Carlo method for computing the phase behavior of systems with strong, extremely short-ranged attractions. For generic ...
Hard-sphere crystallization gets rarer with increasing dimension
(PHYSICAL REVIEW E, 2009-12)
Hard-sphere crystallization gets rarer with increasing dimension.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2009-12)
We recently found that crystallization of monodisperse hard spheres from the bulk fluid faces a much higher free-energy barrier in four than in three dimensions at equivalent supersaturation, due to the increased geometrical ...
Dynamical heterogeneity in a glass-forming ideal gas.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2008-07)
We conduct a numerical study of the dynamical behavior of a system of three-dimensional "crosses," particles that consist of three mutually perpendicular line segments of length sigma rigidly joined at their midpoints. In ...
Geometrical frustration: a study of four-dimensional hard spheres.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2009-03)
The smallest maximum-kissing-number Voronoi polyhedron of three-dimensional (3D) Euclidean spheres is the icosahedron, and the tetrahedron is the smallest volume that can show up in Delaunay tessellation. No periodic lattice ...
