    • Assembly of hard spheres in a cylinder: a computational and experimental study 

      Fu, Lin; Bian, C; IV, CWS; Cruz, DF; López, GP; Charbonneau, Patrick (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 

      Berthier, Ludovic; Charbonneau, Patrick; Coslovich, Daniele; Ninarello, Andrea; Ozawa, M; Yaida, Sho (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 

      Charbonneau, Patrick; Berthier, Ludovic; Kundu, Joyjit
      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 ...
    • Clustering and assembly dynamics of a one-dimensional microphase former. 

      Charbonneau, Patrick; Hu, Yi (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 ...
    • Correlation lengths in quasi-one-dimensional systems via transfer matrices 

      Charbonneau, Patrick; Hu, Yi; Fu, Lin (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 ...
    • Gardner Phenomenology in Minimally Polydisperse Crystalline Systems 

      Charbonneau, Patrick; Corwin, Eric I; Fu, Lin; Tsekenis, Georgios; Naald, Michael van der
      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 

      Behringer, Robert P; Clark, Abram H
      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 

      Berthier, Ludovic; Charbonneau, Patrick; Flenner, E; Zamponi, Francesco (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 ...
    • MC-DEM: a novel simulation scheme for modeling dense granular media 

      Behringer, Robert P; Brodu, N; Dijksman, JA
      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 ...
    • Microphase Equilibrium and Assembly Dynamics 

      Zhuang, Y; Charbonneau, Patrick (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 ...
    • Origin of Ultrastability in Vapor-Deposited Glasses. 

      Berthier, Ludovic; Charbonneau, Patrick; Flenner, Elijah; Zamponi, Francesco (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 ...
    • Phase diagram and aggregation dynamics of a monolayer of paramagnetic colloids 

      Charbonneau, Patrick; Detwiler, Paige; Pham, AT; Socolar, Joshua ES; Yellen, Benjamin; Zhuang, Y (2017-06-01)
      We have developed a tunable colloidal system and a corresponding simulation model for studying the phase behavior of particles assembling under the influence of long-range magnetic interactions. A monolayer of paramagnetic ...
    • Temperature-dependent non-covalent protein-protein interactions explain normal and inverted solubility in a mutant of human gamma D-crystallin 

      Charbonneau, Patrick; Khan, Amir R; James, Susan; Quinn, Michelle K; Altan, Irem; McManus, Jennifer J
      Protein crystal production is a major bottleneck for the structural characterisation of proteins. To advance beyond large-scale screening, rational strategies for protein crystallization are crucial. Understanding ...
    • The Jamming point street-lamp in the world of granular media 

      Behringer, Robert P; Coulais, C; Dauchot, O
      The Jamming of soft spheres at zero temperature, the J-point, has been extensively studied both numerically and theoretically and can now be considered as a safe location in the space of models, where a street lamp has been ...
