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…
Vortex pinning by a columnar defect in planar superconductors with point disorder
Anatoli Polkovnikov, Yariv Kafri, David R. Nelson
We study the effect of a single columnar pin on a dimensional array of vortex lines in planar type II superconductors in the presence of point disorder. In large samples, t…
Spherical Crystallography: Virus Buckling and Grain Boundary Scars
David R. Nelson
Ordered states on spheres require a minimum number of topological defects. For the case of crystalline order, triangular lattices must be interrupted by an array of at least 12 fiv…
A Quasispecies on a Moving Oasis
Michael M. Desai, David R. Nelson
A population evolving in an inhomogeneous environment will adapt differently to different regions. We study the conditions under which such a population can maintain adaptations to…
Statistical Physics of Unzipping DNA
David R. Nelson
The denaturation of double-stranded DNA as function of force and temperature is discussed. At room temperature, sequence heterogeneity dominates the physics of single molecule forc…
