An alternative explanation is that the flux liquid simply becomes more entangled and viscous as its density increases with increasing field. Flux-line entanglement will prevent crystallization and produce instead a nonequilibrium but continuous ``polymer''-glass transition if the barriers to line crossing are sufficiently high. See Refs. 3 and 8. The hysterisis loops associated with first-order freezing would slowly go away as crystallization became more difficult for a fixed cooling rate. The low-temperature dynamics of this polymer glass in the presence of point disorder should be similar to that predicted by the collective pinning theory (Ref. 7), with a polymeric shear modulus replacing the usual elastic constant c66.

In the flux liquid, ``thick'' means sample dimensions large compared to an entanglement length so that boson statistics are applicable (Ref. 3). Deep in the Bose glass, statistics are irrelevant because the fictitious quantum ``particles'' are localized. The thickness dependence of the resistivity in this regime is discussed in Sec. IV.

We assume line-crossing barriers are finite. Two distinct vortex lines may merge to within a coherence length of each other as z varies and then separate again in two distinct trajectories. The thermal average in (3.1) automatically includes a sum over both the ``direct'' and ``exchange'' vortex reconnection possibilities.

If one lets the interplanar Josephson coupling in Ref. 78 tend to zero, the lattice superconductor reduces to a stack of decoupled planes. The discreteness of the underlying model then does have important consequences. It can be shown that only for fillings f < case 1 over 12 will discreteness not affect the continuous nature of the melting transition.

Since f = case 1 over 6 in Ref. 78, results for this model in the strongly anisotropic limit are not directly applicable to the cuprate superconductors.
