    • Continuum-type stability balloon in oscillated granular layers 

      De Bruyn, John R.; Bizon, C.; Shattuck, M. D.; Goldman, Daniel I.; Swift, J. B.; Swinney, Harry L. (Georgia Institute of TechnologyAmerican Physical Society, 1998-08-17)
      The stability of convection rolls in a fluid heated from below is limited by secondary instabilities, including the skew-varicose and crossroll instabilities. We observe a stability boundary defined by these same instabilities ...

    • Kink-induced transport and segregation in oscillated granular layers 

      Moon, Sung Joon; Goldman, Daniel I.; Swift, J. B.; Swinney, Harry L. (Georgia Institute of TechnologyAmerican Physical Society, 2003-09-26)
      We use experiments and molecular dynamics simulations of vertically oscillated granular layers to study horizontal particle segregation induced by a kink (a boundary between domains oscillating out of phase). Counterrotating ...

    • Noise, coherent fluctuations, and the onset of order in an oscillated granular fluid 

      Goldman, Daniel I.; Swift, J. B.; Swinney, Harry L. (Georgia Institute of TechnologyAmerican Physical Society, 2004-04-30)
      We study fluctuations in a vertically oscillated layer of grains below the critical acceleration for the onset of ordered standing waves. As onset is approached, transient disordered waves with a characteristic length scale ...
