Query: Low Temperature Behavior of the Vortex Lattice in Unconventional
  Superconductors   We study the effect of the superconducting gap nodes on the vortex lattice
properties of high temperature superconductors at very low temperatures. The
nonlinear, nonlocal and nonanalytic nature of this effect is shown to have
measurable consequences for the vortex lattice geometry and the effective
penetration depth in the mixed state as measured by muon-spin-rotation
experiments.
