A New Phenomenology for the Disordered Mixed Phase

A universal phase diagram for type-II superconductors with weak point pinning disorder is proposed. In this phase diagram, two thermodynamic phase transitions generically separate a "Bragg glass" from the disordered liquid. Translational correlations in the intervening "multi-domain glass" phase are argued to exhibit a significant degree of short-range order. This phase diagram differs significantly from the currently accepted one, but provides a more accurate description of experimental data on high and low-Tc materials, simulations and current theoretical understanding.
