Correlation Lengths in the Vortex Line Liquid of a High- $T_{c}$ Superconductor

Abstract

We use the three dimensional uniformly frustrated $XY$ model as a model for a high temperature superconductor in an applied magnetic field and explicitly measure the longitudinal correlation length $ξ_{z}$ in the vortex line liquid phase. We determine the scaling of $ξ_{z}$ with magnetic field and system anisotropy close to the vortex lattice melting transition. We apply our results to determine the extent of longitudinal correlations in YBCO just above melting.
