A local view on the role of friction and shape
(EPJ Web of Conferences, 2017)Leibniz said "Naturam cognosci per analogiam": nature is understood by making analogies. This statement describes a seminal epistemological principle. But one has to be aware of its limitations: quantum mechanics for example ... -
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 ... -
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 ... -
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 ... -
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 ... -
Comment on "kosterlitz-Thouless-type caging-uncaging transition in a quasi-one-dimensional hard disk system"
(Physical Review Research, 2021-09-01)Huerta [Phys. Rev. Research 2, 033351 (2020)2643-156410.1103/PhysRevResearch.2.033351] report a power-law decay of positional order in numerical simulations of hard disks confined within hard parallel walls, which they interpret ... -
Correlation lengths in quasi-one-dimensional systems via transfer matrices
(Molecular Physics, 2018-06)© 2018 Informa UK Limited, trading as Taylor & Francis Group. Using transfer matrices up to next-nearest-neighbour interactions, we examine the structural correlations of quasi-one-dimensional systems of hard disks confined ... -
Finite Dimensional Vestige of Spinodal Criticality above the Dynamical Glass Transition.
(Physical review letters, 2020-09)Finite dimensional signatures of spinodal criticality are notoriously difficult to come by. The dynamical transition of glass-forming liquids, first described by mode-coupling theory, is a spinodal instability preempted ... -
Finite-size effects in the microscopic critical properties of jammed configurations: A comprehensive study of the effects of different types of disorder.
(Physical review. E, 2021-07)Jamming criticality defines a universality class that includes systems as diverse as glasses, colloids, foams, amorphous solids, constraint satisfaction problems, neural networks, etc. A particularly interesting feature ... -
Gardner Phenomenology in Minimally Polydisperse Crystalline Systems
We study the structure and dynamics of crystals of minimally polydisperse hard spheres at high pressures. Structurally, they exhibit a power-law scaling in their probability distribution of weak forces and small interparticle ... -
Granular Impact Dynamics: Acoustics and Fluctuations
In the corresponding fluid dynamics video, created for the APS DFD 2012 Gallery of Fluid Motion, we show high-speed videos of 2D granular impact experiments, where an intruder strikes a collection of bidisperse photoelastic ... -
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 ... -
Local dynamical heterogeneity in glass formers
(2021-09-24)We study the local dynamical fluctuations in glass-forming models of particles embedded in $d$-dimensional space, in the mean-field limit of $d\to\infty$. Our analytical calculation reveals that single-particle observables, ... -
MC-DEM: a novel simulation scheme for modeling dense granular media
This article presents a new force model for performing quantitative simulations of dense granular materials. Interactions between multiple contacts (MC) on the same grain are explicitly taken into account. Our readily applicable ... -
Mean-Field Caging in a Random Lorentz Gas.
(The journal of physical chemistry. B, 2021-06-07)The random Lorentz gas (RLG) is a minimal model of both percolation and glassiness, which leads to a paradox in the infinite-dimensional, d → ∞ limit: the localization transition is then expected to be continuous for the ... -
Memory Formation in Jammed Hard Spheres.
(Physical review letters, 2021-02)Liquids equilibrated below an onset condition share similar inherent states, while those above that onset have inherent states that markedly differ. Although this type of materials memory was first reported in simulations ... -
Microphase Equilibrium and Assembly Dynamics
(2017-08-23)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 ... -
Numerical transfer matrix study of frustrated next-nearest-neighbor Ising models on square lattices
(Physical Review B, 2021-10-01)Ising models with frustrated next-nearest-neighbor interactions present a rich array of modulated phases. These phases, however, assemble and relax slowly, which hinders their computational study. In two dimensions, strong ... -
Origin of Ultrastability in Vapor-Deposited Glasses.
(Physical review letters, 2017-11)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 ...
