TL;DR: In this article, an extensive scaling analysis of the transport properties in twinned YBaCuO(123) crystals was performed and the predicted change in the universality class of the Boseglass to liquid transition when the magnetic field is applied at small angles away from the direction of the correlated defects.
Abstract: Using an extensive scaling analysis of the transport properties in twinned YBaCuO(123) crystals we have experimentally found the predicted change in the universality class of the Bose-glass to liquid transition when the magnetic field is applied at small angles away from the direction of the correlated defects. The new dynamical critical exponent is s'=1.1 +/-0.2.

TL;DR: In this paper, the Hansen-Verlet criterion is used to explain the jump in resistance at the melting transition, which is experimentally observed to be constant, independent of magnetic field (vortex density).
TL;DR: In this article, it was shown that d-wave superconductivity is compatible with a localized normal state when the coherence length is of the order of the lattice constant.
Abstract: We address the question of whether an anisotropic gap of symmetry is compatible with localized states in the normal phase. The issue is important for high- superconductors for which a superconductor-to-insulator transition is observed, together with a number of experiments that support d-wave pairing. We prove that d-wave superconductivity is compatible with a localized normal state. When the coherence length is of the order of the lattice constant, the effects of localization are important. We find a re-entrant behaviour of superconductivity in the strongly disordered phase.
