Superconducting Coherence in a Vortex Line Liquid; Simulations with   Finite \lambda
  We carry out simulations of a lattice London superconductor in a magnetic field B, with a finite magnetic penetration length \lambda. We find that superconducting coherence parallel to B persists into the vortex line liquid. We argue that the length scale relevant to this effect is \Lambda=\phi_0^2/8\pi T_m.
