A Ball in a Groove
Thomas C. Halsey, Deniz Ertas
We study the static equilibrium of an elastic sphere held in a rigid groove by gravity and frictional contacts, as determined by contact mechanics. As a function of the opening ang…
Multifractal Dimensions for Branched Growth
Thomas C. Halsey, Katsuya Honda, Bertrand Duplantier
A recently proposed theory for diffusion-limited aggregation (DLA), which models this system as a random branched growth process, is reviewed. Like DLA, this process is stochastic,…
Self-Organized Short-Term Memories
S. N. Coppersmith, T. C. Jones, L. P. Kadanoff +5
We report short-term memory formation in a nonlinear dynamical system with many degrees of freedom. The system ``remembers'' a sequence of impulses for a transient period, but it c…
Fluctuation-Induced Interactions between Rods on a Membrane
Ramin Golestanian, Mark Goulian, Mehran Kardar
We consider the interaction between two rods embedded in a fluctuating surface. The modification of fluctuations by the rods leads to an attractive long-range interaction between t…
A Model for Force Fluctuations in Bead Packs
S. N. Coppersmith, C. -h. Liu, S. Majumdar +2
We study theoretically the complex network of forces that is responsible for the static structure and properties of granular materials. We present detailed calculations for a model…
Shape Fluctuations of a Droplet Containing a Polymer
M. Goulian, S. T. Milner
We consider the problem of an ideal polymer confined in a droplet. When the droplet radius is smaller than the (unconfined) polymer radius of gyration, the polymer entropy will dep…
