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 ...
Dimensional dependence of the Stokes-Einstein relation and its violation.
(J Chem Phys, 2013-10-28)
We generalize to higher spatial dimensions the Stokes-Einstein relation (SER) as well as the leading correction to diffusivity in finite systems with periodic boundary conditions, and validate these results with numerical ...
Numerical detection of the Gardner transition in a mean-field glass former.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2015-07)
Recent theoretical advances predict the existence, deep into the glass phase, of a novel phase transition, the so-called Gardner transition. This transition is associated with the emergence of a complex free energy landscape ...
Numerical and theoretical study of a monodisperse hard-sphere glass former
(PHYSICAL REVIEW E, 2010-04)
Kinetic Monte Carlo simulations for birefringence relaxation of photo-switchable molecules on a surface.
(J Chem Phys, 2016-03-14)
Recent experiments have demonstrated that in a dense monolayer of photo-switchable dye methyl-red molecules the relaxation of an initial birefringence follows a power-law decay, typical for glass-like dynamics. The slow ...
Phase ordering of zig-zag and bow-shaped hard needles in two dimensions.
(J Chem Phys, 2015-09-21)
We perform extensive Monte Carlo simulations of a two-dimensional bent hard-needle model in both its chiral zig-zag and its achiral bow-shape configurations and present their phase diagrams. We find evidence for a variety ...
Hopping and the Stokes-Einstein relation breakdown in simple glass formers.
(Proc Natl Acad Sci U S A, 2014-10-21)
One of the most actively debated issues in the study of the glass transition is whether a mean-field description is a reasonable starting point for understanding experimental glass formers. Although the mean-field theory ...
Decorrelation of the static and dynamic length scales in hard-sphere glass formers.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2013-04)
We show that, in the equilibrium phase of glass-forming hard-sphere fluids in three dimensions, the static length scales tentatively associated with the dynamical slowdown and the dynamical length characterizing spatial ...
Geometrical frustration and static correlations in hard-sphere glass formers.
(J Chem Phys, 2013-03-28)
We analytically and numerically characterize the structure of hard-sphere fluids in order to review various geometrical frustration scenarios of the glass transition. We find generalized polytetrahedral order to be correlated ...
Hard-sphere crystallization gets rarer with increasing dimension
