Non-Hermitian Luttinger liquids and flux line pinning in planar superconductors
Non-Hermitian Luttinger liquids and flux line pinning in planar superconductors
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 planar superconductor. This problem can be mapped onto the physics of a Luttinger liquid of interacting bosons …
