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))

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 Monte Carlo simulations of the cluster-crystal-forming penetrable sphere model.
(J Chem Phys, 2012-06-07)
Certain models with purely repulsive pair interactions can form cluster crystals with multiply-occupied lattice sites. Simulating these models' equilibrium properties is, however, quite challenging. Here, we develop an expanded ...
Phase transformations in binary colloidal monolayers.
(Soft Matter, 2015-03-28)
Phase transformations can be difficult to characterize at the microscopic level due to the inability to directly observe individual atomic motions. Model colloidal systems, by contrast, permit the direct observation of individual ...
Reentrant and isostructural transitions in a cluster-crystal former.
(Phys Rev Lett, 2010-12-10)
We study the low-temperature behavior of a simple cluster-crystal forming system through simulation. We find the phase diagram to be hybrid between the Gaussian core model and the penetrable sphere model. The system additionally ...
(Arch Biochem Biophys, 2016-07-15)
Crystallization is a key step in macromolecular structure determination by crystallography. While a robust theoretical treatment of the process is available, due to the complexity of the system, the experimental process ...
Microphase Equilibrium and Assembly Dynamics
Despite many attempts, ordered equilibrium microphases have yet to be obtained in experimental colloidal suspensions. The recent computation of the equilibrium phase diagram of a microscopic, particle-based microphase former ...
Out-of-equilibrium dynamical fluctuations in glassy systems
(Journal of Chemical Physics, 2004-11-22)
In this paper we extend the earlier treatment of out-of-equilibrium mesoscopic fluctuations in glassy systems in several significant ways. First, via extensive simulations, we demonstrate that models of glassy behavior without ...
