Query: Percolation transition of the vortex lattice and c-axis resistivity in
  high-temperature superconductors   We use the three-dimensional Josephson junction array system as a model for
studying the temperature dependence of the c-axis resistivity of high
temperature superconductors, in the presence of an external magnetic field H
applied in the c-direction. We show that the temperature at which the
dissipation becomes different from zero corresponds to a percolation transition
of the vortex lattice. In addition, the qualitative features of the resistivity
vs. temperature curves close to the transition are obtained starting from the
geometrical configurations of the vortices. The results apply to the cases H
greater than 0 and H=0.
