【 摘 要 】

The three-dimensional uniformly frustrated XY model is simulated to search for a predicted vortex loop transition within the vortex line liquid phase of a strongly type-II superconductor in an applied magnetic field. Results are shown to strongly depend on the precise scheme used to trace out vortex line paths. While we find evidence for a transverse vortex path percolation transition, no signal of this transition is found in the specific heat.
