    • For free boundary conditions along z^, as opposed to the periodic boundary conditions of the analog 2D bosons, a sharp KT transition does not exist; nevertheless, a strong crossover should remain. See

    • Since we work in the Helmholtz ensemble at fixed Bz^, our configurations are constrained to satisfy nx,y(q=0)=0. Hence a direct computation of W must always rigorously vanish in each individual configuration. Nevertheless, we can compute the correct value of 〈W2〉 that one would find in the Gibbs ensemble [with no constraint on nx,y(q=0)] by taking an appropriate q→0 limit. This is done by considering only one component, say Wy2, and taking q in the x-y plane transverse to this direction, i.e., qz=qy=0 as qx→0. This procedure leads to a factor of 2 correction to the KT transition temperature reported in Ref. [c11]. We thank A. P. Young for clarification on this point.

    • (unpublished) also suggest Λ as an important length in the vortex liquid. However, their arguments seem unrelated to the KT transition discussed here, and they suggest that the intermediate superconducting line liquid persists even for Lz→∞.
