Lyapunov exponent and susceptibility
Lyapunov exponents characterize the chaotic nature of dynamical systems by quantifying the growth rate of uncertainty associated with imperfect measurement of the initial conditions. Finite-time estimates of the exponent, ...
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 ...
Application of Edwards' statistical mechanics to high-dimensional jammed sphere packings.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2010-11)
The isostatic jamming limit of frictionless spherical particles from Edwards' statistical mechanics [Song et al., Nature (London) 453, 629 (2008)] is generalized to arbitrary dimension d using a liquid-state description. ...
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 ...
Assembly of hard spheres in a cylinder: a computational and experimental study
Hard spheres are an important benchmark of our understanding of natural and synthetic systems. In this work, colloidal experiments and Monte Carlo simulations examine the equilibrium and out-of-equilibrium assembly of hard ...
Linking dynamical heterogeneity to static amorphous order
(Journal of Statistical Mechanics: Theory and Experiment, 2016-07-01)
© 2016 IOP Publishing Ltd and SISSA Medialab srl. Glass-forming liquids grow dramatically sluggish upon cooling. This slowdown has long been thought to be accompanied by a growing correlation length. Characteristic dynamical ...
Highly parallel acoustic assembly of microparticles into well-ordered colloidal crystallites.
(Soft Matter, 2016-01-21)
The precise arrangement of microscopic objects is critical to the development of functional materials and ornately patterned surfaces. Here, we present an acoustics-based method for the rapid arrangement of microscopic particles ...
Numerical and theoretical study of a monodisperse hard-sphere glass former.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2010-04)
There exists a variety of theories of the glass transition and many more numerical models. But because the models need built-in complexity to prevent crystallization, comparisons with theory can be difficult. We study the ...
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)
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, ...
