Crystalline Particle Packings on a Sphere with Long Range Power Law Potentials
Mark J. Bowick, Angelo Cacciuto, David R. Nelson +1
The original Thomson problem of "spherical crystallography" seeks the ground state of electron shells interacting via the Coulomb potential; however one can also study crystalline…
Sequence heterogeneity and the dynamics of molecular motors
Yariv Kafri, David R. Nelson
The effect of sequence heterogeneity on the dynamics of molecular motors is reviewed and analyzed using a set of recently introduced lattice models. First, we review results for th…
Direct Visualization of Dislocation Dynamics in Grain Boundary Scars
Peter Lipowsky, Mark J. Bowick, Jan H. Meinke +2
Mesoscale objects with unusual structural features may serve as the analogues of atoms in the design of larger-scale materials with novel optical, electronic or mechanical behaviou…
Unzipping flux lines from extended defects in type-II superconductors
Yariv Kafri, David R. Nelson, Anatoli Polkovnikov
With magnetic force microscopy in mind, we study the unbinding transition of individual flux lines from extended defects like columnar pins and twin planes in type II superconducto…
