    • A microscopic model of the Stokes-Einstein relation in arbitrary dimension. 

      Charbonneau, Patrick; Charbonneau, Benoit; Szamel, Grzegorz (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 ...
    • A nontrivial critical fixed point for replica-symmetry-breaking transitions 

      Charbonneau, Patrick; Yaida, Sho (2017-04-01)
      The transformation of the free-energy landscape from smooth to hierarchical is one of the richest features of mean-field disordered systems. A well-studied example is the de Almeida-Thouless transition for spin glasses in ...
    • Application of Edwards' statistical mechanics to high-dimensional jammed sphere packings 

      Charbonneau, Patrick; Jin, Y; Meyer, S; Song, C; Zamponi, Francesco (PHYSICAL REVIEW E, 2010-11-18)

      Charbonneau, Patrick; Jin, Y; Meyer, S; Song, C; Zamponi, Francesco (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 

      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 ...
    • Characterizing protein crystal contacts and their role in crystallization: rubredoxin as a case study. 

      Charbonneau, Patrick; De Simone, A; Fusco, Diana; Headd, JJ; Wang, J (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. 

      Charbonneau, Patrick; Bruno, Andrew E; Newman, Janet; Snell, Edward H; So, David R; Vanhoucke, Vincent; Watkins, Christopher J; ... (9 authors) (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. 

      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 ...
    • Competition between monomeric and dimeric crystals in schematic models for globular proteins. 

      Charbonneau, Patrick; Fusco, Diana (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. 

      Altan, I; Charbonneau, Patrick; Snell, EH (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. 

      Berthier, Ludovic; Charbonneau, Patrick; Coslovich, Daniele; Ninarello, Andrea; Ozawa, Misaki; Yaida, Sho (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. ...
    • 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 ...

      Charbonneau, Patrick; Fusco, Diana (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 ...

      Charbonneau, Patrick; Ikeda, A; Parisi, G; Zamponi, Francesco (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, ...
