[N]pT ensemble and finite-size-scaling study of the critical isostructural transition in the generalized exponential model of index 4.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2012-10)
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 ...
Equilibrium Phase Behavior of a Continuous-Space Microphase Former.
(Phys Rev Lett, 2016-03-04)
Periodic microphases universally emerge in systems for which short-range interparticle attraction is frustrated by long-range repulsion. The morphological richness of these phases makes them desirable material targets, but ...
Growing timescales and lengthscales characterizing vibrations of amorphous solids.
(Proc Natl Acad Sci U S A, 2016-07-26)
Low-temperature properties of crystalline solids can be understood using harmonic perturbations around a perfect lattice, as in Debye's theory. Low-temperature properties of amorphous solids, however, strongly depart from ...
Erratum: Emergence of limit-periodic order in tiling models (Physical Review E - Statistical, Nonlinear, and Soft Matter Physics (2014) 90 (012136))
(Physical Review E - Statistical, Nonlinear, and Soft Matter Physics, 2016-02-29)
Dimensional dependence of the Stokes-Einstein relation and its violation
(Journal of Chemical Physics, 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 ...
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, ...
Application of Edwards' statistical mechanics to high-dimensional jammed sphere packings
(PHYSICAL REVIEW E, 2010-11-18)
Universal Non-Debye Scaling in the Density of States of Amorphous Solids.
(Phys Rev Lett, 2016-07-22)
At the jamming transition, amorphous packings are known to display anomalous vibrational modes with a density of states (DOS) that remains constant at low frequency. The scaling of the DOS at higher packing fractions remains, ...
Point-to-set lengths, local structure, and glassiness.
(Phys Rev E, 2016-09)
The growing sluggishness of glass-forming liquids is thought to be accompanied by growing structural order. The nature of such order, however, remains hotly debated. A decade ago, point-to-set (PTS) correlation lengths were ...
Universal microstructure and mechanical stability of jammed packings.
(Phys Rev Lett, 2012-11-16)
The mechanical properties of jammed packings depend sensitively on their detailed local structure. Here we provide a complete characterization of the pair correlation close to contact and of the force distribution of jammed ...
