    • Dimensional study of the caging order parameter at the glass transition. 

      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, ...
    • Dimensional study of the dynamical arrest in a random Lorentz gas. 

      Charbonneau, Patrick; Jin, Y (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 ...
    • Hard-sphere crystallization gets rarer with increasing dimension. 

      Charbonneau, Benoit; Charbonneau, Patrick; Fortini, A; van Meel, JA (Phys Rev E Stat Nonlin Soft Matter Phys, 2009-12)
      We recently found that crystallization of monodisperse hard spheres from the bulk fluid faces a much higher free-energy barrier in four than in three dimensions at equivalent supersaturation, due to the increased geometrical ...
    • Numerical detection of the Gardner transition in a mean-field glass former. 

      Charbonneau, Patrick; Jin, Y; Parisi, G; Rainone, C; Seoane, B; Zamponi, Francesco (Phys Rev E Stat Nonlin Soft Matter Phys, 2015-07)
      Recent theoretical advances predict the existence, deep into the glass phase, of a novel phase transition, the so-called Gardner transition. This transition is associated with the emergence of a complex free energy landscape ...
