Dimensional study of the caging order parameter at the glass transition.
(Proc Natl Acad Sci U S A, 2012-08-28)
The glass problem is notoriously hard and controversial. Even at the mean-field level, little is agreed upon regarding why a fluid becomes sluggish while exhibiting but unremarkable structural changes. It is clear, however, ...
Nontrivial Critical Fixed Point for Replica-Symmetry-Breaking Transitions.
(Phys Rev Lett, 2017-05-26)
The transformation of the free-energy landscape from smooth to hierarchical is one of the richest features of mean-field disordered systems. A well-studied example is the de Almeida-Thouless transition for spin glasses in ...
[N]pT ensemble and finite-size-scaling study of the critical isostructural transition in the generalized exponential model of index 4
(Physical Review E - Statistical, Nonlinear, and Soft Matter Physics, 2012-10-15)
First-order transitions of system where both lattice site occupancy and lattice spacing fluctuate, such as cluster crystals, cannot be efficiently studied by traditional simulation methods, which necessarily fix one of these ...
Hard-sphere crystallization gets rarer with increasing dimension

Erratum: [N]pT ensemble and finite-size-scaling study of the critical isostructural transition in the generalized exponential model of index 4

How to create equilibrium vapor-deposited glasses
Glass films created by vapor-depositing molecules onto a substrate can exhibit properties similar to those of ordinary glasses aged for thousands of years. It is believed that enhanced surface mobility is the mechanism that ...
Glass transition and random close packing above three dimensions.
(Phys Rev Lett, 2011-10-28)
Motivated by a recently identified severe discrepancy between a static and a dynamic theory of glasses, we numerically investigate the behavior of dense hard spheres in spatial dimensions 3 to 12. Our results are consistent ...
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 ...
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 ...
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 ...
