Mode-coupling theory
(Journal of Statistical Mechanics: Theory and Experiment, 2005-05-01)
In this set of lecture notes we review the mode-coupling theory of the glass transition
from several perspectives. First, we derive mode-coupling equations for the description
of density fluctuations from microscopic ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Hard-sphere crystallization gets rarer with increasing dimension
