Correlation Lengths in the Vortex Line Liquid of a High-Tc Superconductor
نویسنده
چکیده
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 jz in the vortex line liquid phase. We determine the scaling of jz 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. [S0031-9007(99)08645-7]

Superconducting Coherence in a Vortex Line Liquid: Simulations with Finite lambda.
In high Tc superconductors, thermal fluctuations are believed to melt the ground state vortex line lattice at temperatures well below the mean field Hc2 line [1,2]. The resulting vortex line liquid has received intense theoretical and experimental study. In particular, recent “flux transformer” experiments [3,4] on YBCO show that superconducting coherence parallel to the applied magnetic field ...
متن کاملVortex-line fluctuations in model high-temperature superconductors.
We carry out Monte Carlo simulations of the uniformly frustrated three dimensional XY model, as a model for vortex line fluctuations in a high Tc superconductor in an external magnetic field. A density of vortex lines of f = 1/25 is considered. We find two sharp phase transitions. The low T superconducting phase is an ordered vortex line lattice. The high T normal phase is a vortex line liquid,...

The phase transition ‘‘triangular lattice–vortex liquid’’ in layered highTc superconductors in the presence of pinning centers is studied. A two-dimensional system of vortices simulating the superconducting layers in a high-Tc Shubnikov phase is calculated by the Monte Carlo method. It was found that in the presence of defects the melting of the vortex lattice proceeds in two stages: First, the...
متن کاملPhase transitions and vortex-line entanglement in a model high-temperature superconductor.
We carry out Monte Carlo simulations of the uniformly frustrated three dimensional XY model, as a model for vortex line fluctuations in high temperature superconductors in an applied magnetic field. We show, comparing systems of different size, that there are two distinct phase transitions. At a lower Tc⊥, the vortex lattice melts, and coherence is lost in planes perpendicular to the magnetic f...
متن کاملVortices and 2D Bosons: A Path-Integral Monte Carlo Study
The vortex system in a high-Tc superconductor has been studied numerically using the mapping to 2D bosons and the Path Integral Monte Carlo method. We find a single first-order transition from an Abrikosov lattice to an entangled vortex liquid. The transition is characterized by an entropy jump of ∆S ≈ 0.27kB per degree of freedom and a Lindemann number cL ≈ 0.29. At low fields, λ ≈ a0, the den...
