Geometrical Frustration in Two Dimensions: Idealizations and Realizations of a Hard Disc Fluid in Negative Curvature
Carl D. Modes, Randall D. Kamien
We examine a simple hard disc fluid with no long range interactions on the two dimensional space of constant negative Gaussian curvature, the hyperbolic plane. This geometry provid…
Dynamics of shallow impact cratering
M. A. Ambroso, R. D. Kamien, D. J. Durian
We present data for the time-dependence of wooden spheres penetrating into a loose non-cohesive packing of glass beads. The stopping time is a factor of three longer than the time…
Entropically Driven Helix Formation
Yehuda Snir, Randall D. Kamien
The helix is a ubiquitous motif for biopolymers. We propose a heuristic, entropically based model that predicts helix formation in a system of hard spheres and semiflexible tubes.…
Self-Consistent Field Theory of Multiply-Branched Block Copolymer Melts
Gregory M. Grason, Randall D. Kamien
We present a numerical algorithm to evaluate the self-consistent field theory for melts composed of block copolymers with multiply-branched architecture. We present results for the…
Interfaces in Diblocks: A Study of Miktoarm Star Copolymers
Gregory M. Grason, Randall D. Kamien
We study AB miktoarm star block copolymers in the strong segregation limit, focussing on the role that the AB interface plays in determining the phase behavior. We develop an e…
Elongation and fluctuations of semi-flexible polymers in a nematic solvent
Z. Dogic, J. Zhang, A. W. C. Lau +7
We directly visualize single polymers with persistence lengths ranging from to 16 m, dissolved in the nematic phase of rod-like {\it fd} virus. Polymers with suffi…
