ALERT: This system is being upgraded on Tuesday December 12. It will not be available
for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

A microscopic model of the Stokes-Einstein relation in arbitrary dimension.
(The Journal of chemical physics, 2018-06)The Stokes-Einstein relation (SER) is one of the most robust and widely employed results from the theory of liquids. Yet sizable deviations can be observed for self-solvation, which cannot be explained by the standard ... -
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. ... -
Assembly of hard spheres in a cylinder: a computational and experimental study
(2017-03-10)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 ... -
Bypassing sluggishness: SWAP algorithm and glassiness in high dimensions
The recent implementation of a swap Monte Carlo algorithm (SWAP) for polydisperse mixtures fully bypasses computational sluggishness and closes the gap between experimental and simulation timescales in physical dimensions ... -
Characterization and efficient Monte Carlo sampling of disordered microphases.
(The Journal of chemical physics, 2021-06)The disordered microphases that develop in the high-temperature phase of systems with competing short-range attractive and long-range repulsive (SALR) interactions result in a rich array of distinct morphologies, such as ... -
Characterizing protein crystal contacts and their role in crystallization: rubredoxin as a case study.
(Soft Matter, 2014-01-14)The fields of structural biology and soft matter have independently sought out fundamental principles to rationalize protein crystallization. Yet the conceptual differences and the limited overlap between the two disciplines ... -
Classification of crystallization outcomes using deep convolutional neural networks.
(PloS one, 2018-01)The Machine Recognition of Crystallization Outcomes (MARCO) initiative has assembled roughly half a million annotated images of macromolecular crystallization experiments from various sources and setups. Here, state-of-the-art ... -
Clustering and assembly dynamics of a one-dimensional microphase former.
(Soft matter, 2018-03-26)Both ordered and disordered microphases ubiquitously form in suspensions of particles that interact through competing short-range attraction and long-range repulsion (SALR). While ordered microphases are more appealing materials ... -
Communication: Weakening the critical dynamical slowing down of models with SALR interactions.
(The Journal of chemical physics, 2022-11)In systems with frustration, the critical slowing down of the dynamics severely impedes the numerical study of phase transitions for even the simplest of lattice models. In order to help sidestep the gelation-like sluggishness, ... -
Competition between monomeric and dimeric crystals in schematic models for globular proteins.
(J Phys Chem B, 2014-07-17)Advances in experimental techniques and in theoretical models have improved our understanding of protein crystallization. However, they have also left open questions regarding the protein phase behavior and self-assembly ... -
Computational crystallization.
(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 ... -
Configurational entropy measurements in extremely supercooled liquids that break the glass ceiling.
(Proceedings of the National Academy of Sciences of the United States of America, 2017-10-10)Liquids relax extremely slowly on approaching the glass state. One explanation is that an entropy crisis, because of the rarefaction of available states, makes it increasingly arduous to reach equilibrium in that regime. ... -
Correction to: Obtaining Soft Matter Models of Proteins and their Phase Behavior.
(Methods in molecular biology (Clifton, N.J.), 2019-01)The acknowledgement section text has been updated in the chapter. -
Crystallization of asymmetric patchy models for globular proteins in solution.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2013-07)Asymmetric patchy particle models have recently been shown to describe the crystallization of small globular proteins with near-quantitative accuracy. Here, we investigate how asymmetry in patch geometry and bond energy ... -
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 ... -
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, ... -
Dimensional study of the dynamical arrest in a random Lorentz gas.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2015-04)The random Lorentz gas (RLG) is a minimal model for transport in heterogeneous media. Upon increasing the obstacle density, it exhibits a growing subdiffusive transport regime and then a dynamical arrest. Here, we study ... -
Dynamical heterogeneity in a glass-forming ideal gas.
(Phys Rev E Stat Nonlin Soft Matter Phys, 2008-07)We conduct a numerical study of the dynamical behavior of a system of three-dimensional "crosses," particles that consist of three mutually perpendicular line segments of length sigma rigidly joined at their midpoints. In ... -
Dynamics around the Site Percolation Threshold on High-Dimensional Hypercubic Lattices
Recent advances on the glass problem motivate reexamining classical models of percolation. Here, we consider the displacement of an ant in a labyrinth near the percolation threshold on cubic lattices both below and above ...
