Dynamics of Molecular Motors with Finite Processivity on Heterogeneous Tracks
Yariv Kafri, David K. Lubensky, David R. Nelson
The dynamics of molecular motors which occasionally detach from a heterogeneous track like DNA or RNA is considered. Motivated by recent single molecule experiments, we study a sim…
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…
Non-Hermitian Luttinger liquids and flux line pinning in planar superconductors
Ian Affleck, Walter Hofstetter, David R. Nelson +1
As a model of thermally excited flux liquids connected by a weak link, we study the effect of a single line defect on vortex filaments oriented parallel to the surface of a thin pl…
Defect generation and deconfinement on corrugated topographies
Vincenzo Vitelli, David R. Nelson
We investigate topography-driven generation of defects in liquid crystals films coating frozen surfaces of spatially varying Gaussian curvature whose topology does not automaticall…
