    • Note that the existence of a finite-temperature phase transition in the numerical simulations of a 3D VG appears to be model dependent;

    • Also, it is useful to point out that most numerical simulations have considered the gauge glass rather than the vortex glass, i.e., a model with random magnetic flux rather than one with a uniform magnetic field and random point disorder. Both models are expected to exhibit similar properties. More work is needed, however, to establish this convincingly.

    • The Bose-glass model predicts a critical-scaling equation which is the same as the one predicted by the VG model, i.e., Eq. (5), with different critical exponents z prime and ν prime, however. These Bose-glass critical exponents can be simply expressed in the VG critical exponents z and nu, viz z prime = 1/2 (3z+1) and ν prime = case 2 over 3 nu. Critical scaling of the nonlinear current-voltage characteristics in itself therefore cannot be used to distinguish between the two models. However, by investigating critical scaling at different angles between the magnetic field and the sample; it can be deduced which model is relevant; see Ref. 34.
