Morphology of Nematic and Smectic Vesicles
Xiangjun Xing, Homin Shin, Mark J. Bowick +3
Recent experiments on vesicles formed from block copolymers with liquid-crystalline side-chains reveal a rich variety of vesicle morphologies. The additional internal order ("struc…
Filling the void in confined polymer nematics: phase transitions in a minimal model of dsDNA packing
Homin Shin, Gregory M. Grason
Inspired to understand the complex spectrum of space-filling organizations the dsDNA genome within the capsid of bacterial viruses, we study a minimal, coarse-grained model of sing…
Structural Reorganization of Parallel Actin Bundles by Crosslinking Proteins: Incommensurate States of Twist
Homin Shin, Gregory M. Grason
We construct a coarse-grained model of parallel actin bundles crosslinked by compact, globular bundling proteins, such as fascin and espin, necessary components of filapodial and m…
Cooperativity and Frustration in Protein-Mediated Parallel Actin Bundles
Homin Shin, Kirstin R. Purdy Drew, James R. Bartles +2
We examine the mechanism of bundling of cytoskeletal actin filaments by two representative bundling proteins, fascin and espin. Small-angle X-ray studies show that increased bindin…
Mesophases of soft-sphere aggregates
Homin Shin, Gregory M. Grason, Christian D. Santangelo
Soft spheres interacting via a hard core and range of attractive and repulsive "soft-shoulder" potentials self-assemble into clusters forming a variety of mesophases. We combine a…
Topological Defects in Spherical Nematics
Homin Shin, Mark J. Bowick, Xiangjun Xing
We study the organization of topological defects in a system of nematogens confined to the two-dimensional sphere (S^2). We first perform Monte Carlo simulations of a fluid system…
