Repulsive vortex interactions destroy the Mott insulator phase predicted to occur at B = B<sub>Φ</sub>. For ratios of the penetration depth to average defect distance λ/d ≤ 1 remnants of the Mott insulator singularities remain visible in the magnetization, the bulk modulus, and the magnetization relaxation, as B is varied near B<sub>Φ</sub>. For λ ≥ d, the ensuing weakly pinned Bose glass is characterized by a soft Coulomb gap in the distribution of pinning energies.4845 - 4848 page(s)application/pdfenIn CopyrightWeakly pinned Bose glass vs Mott insulator phase in superconductorsArticle - RefereedPhysical Review Lettershttps://doi.org/10.1103/PhysRevLett.78.48457825
