    • Correlation between Voronoi volumes in disc packings 

      Zhao, Song-Chuan; Sidle, Stacy; Swinney, Harry L; Schröter, Matthias (EPL (Europhysics Letters), 2012-02-01)
      We measure the two-point correlation of free Voronoi volumes in binary disc packings, where the packing fraction $\phi_{\rm avg}$ ranges from 0.8175 to 0.8380. We observe short-ranged correlations over the whole range of ...
    • Nucleation in Sheared Granular Matter. 

      Rietz, Frank; Radin, Charles; Swinney, Harry L; Schröter, Matthias (Physical review letters, 2018-02)
      We present an experiment on crystallization of packings of macroscopic granular spheres. This system is often considered to be a model for thermally driven atomic or colloidal systems. Cyclically shearing a packing of frictional ...
    • Stationary state volume fluctuations in a granular medium. 

      Schröter, Matthias; Goldman, Daniel I; Swinney, Harry L (Physical review. E, Statistical, nonlinear, and soft matter physics, 2005-03-30)
      A statistical description of static granular material requires ergodic sampling of the phase space spanned by the different configurations of the particles. We periodically fluidize a column of glass beads and find that ...
