Breaking the glass ceiling: Configurational entropy measurements in extremely supercooled liquids
(2017-06-01)
Liquids relax extremely slowly on approaching the glass state. One explanation is
that an entropy crisis, due to the rarefaction of available states, makes it increasingly
arduous to reach equilibrium in that regime. Validating ...
Geometrical frustration and static correlations in a simple glass former.
(Phys Rev Lett, 2012-01-20)
We study the geometrical frustration scenario of glass formation for simple hard-sphere
models. We find that the dual picture in terms of defects brings little insight and
no theoretical simplification for the understanding ...
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, ...
[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
(PHYSICAL REVIEW E, 2009-12)
How to create equilibrium vapor-deposited glasses
(2017-08-23)
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 ...
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 ...
[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 ...
Numerical and theoretical study of a monodisperse hard-sphere glass former
(PHYSICAL REVIEW E, 2010-04)
Application of Edwards' statistical mechanics to high-dimensional jammed sphere packings
(PHYSICAL REVIEW E, 2010-11-18)
