    • Emergence of limit-periodic order in tiling models. 

      Marcoux, Catherine; Byington, Travis W; Qian, Zongjin; Charbonneau, Patrick; Socolar, Joshua ES (Phys Rev E Stat Nonlin Soft Matter Phys, 2014-07)
      A two-dimensional (2D) lattice model defined on a triangular lattice with nearest- and next-nearest-neighbor interactions based on the Taylor-Socolar monotile is known to have a limit-periodic ground state. The system reaches ...
    • Hard sphere packings within cylinders. 

      Fu, Lin; Steinhardt, William; Zhao, Hao; Socolar, Joshua ES; Charbonneau, Patrick (Soft Matter, 2016-03-07)
      Arrangements of identical hard spheres confined to a cylinder with hard walls have been used to model experimental systems, such as fullerenes in nanotubes and colloidal wire assembly. Finding the densest configurations, ...
    • Phase diagram and aggregation dynamics of a monolayer of paramagnetic colloids 

      Pham, An T; Zhuang, Yuan; Detwiler, Paige; Socolar, Joshua ES; Charbonneau, Patrick; Yellen, Benjamin B (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 ...
    • Phase transformations in binary colloidal monolayers. 

      Yang, Ye; Fu, Lin; Marcoux, Catherine; Socolar, Joshua ES; Charbonneau, Patrick; Yellen, Benjamin B (Soft Matter, 2015-03-28)
      Phase transformations can be difficult to characterize at the microscopic level due to the inability to directly observe individual atomic motions. Model colloidal systems, by contrast, permit the direct observation of individual ...
    • Reliability of transcriptional cycles and the yeast cell-cycle oscillator. 

      Sevim, Volkan; Gong, Xinwei; Socolar, Joshua ES (PLoS computational biology, 2010)
      A recently published transcriptional oscillator associated with the yeast cell cycle provides clues and raises questions about the mechanisms underlying autonomous cyclic processes in cells. Unlike other biological and synthetic ...
    • Yielding, rigidity, and tensile stress in sheared columns of hexapod granules 

      Zhao, Yuchen; Barés, Jonathan; Socolar, Joshua ES
      Granular packings of non-convex or elongated particles can form free-standing structures like walls or arches. For some particle shapes, such as staples, the rigidity arises from interlocking of pairs of particles, but the ...
