A New Phenomenology for the Disordered Mixed Phase
arXiv:cond-mat/0102168 · doi:10.1142/S021798490100297X
Abstract
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-T materials, simulations and current theoretical understanding.
