Effects of kinked linear defects on planar flux line arrays
Eleni Katifori, David R. Nelson
In the hard core limit, interacting vortices in planar type II superconductors can be modeled as non-interacting one dimensional fermions propagating in imaginary time. We use this…
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…
Vortex wandering in a forest of splayed columnar defects
Jack Lidmar, David R. Nelson, Denis A. Gorokhov
We investigate the scaling properties of single flux lines in a random pinning landscape consisting of splayed columnar defects. Such correlated defects can be injected into Type I…
Interaction effects in non-Hermitian models of vortex physics
Kihong Kim, David R. Nelson
Vortex lines in superconductors in an external magnetic field slightly tilted from randomly-distributed parallel columnar defects can be modeled by a system of interacting bosons i…
Vortex Physics in Confined Geometries
M. Cristina Marchetti, David R. Nelson
Patterned irradiation of cuprate superconductors with columnar defects allows a new generation of experiments which can probe the properties of vortex liquids by forcing them to fl…
B(H) Constitutive Relations Near H_c1 in Disordered Superconductors
Raphael A. Lehrer, David R. Nelson
We provide a self-contained account of the B vs. H constitutive relation near H_c1 in Type II superconductors with various types of quenched random disorder. The traditional Abriko…
Patterned Geometries and Hydrodynamics at the Vortex Bose Glass Transition
M. Cristina Marchetti, David R. Nelson
Patterned irradiation of cuprate superconductors with columnar defects allows a new generation of experiments which can probe the properties of vortex liquids by confining them to…
Superfluid Bosons and Flux Liquids: Disorder, Thermal Fluctuations, and Finite-Size Effects
Uwe C. Täuber, David R. Nelson
The influence of different types of disorder (both uncorrelated and correlated) on the superfluid properties of a weakly interacting or dilute Bose gas, as well as on the correspon…
