Research paperTheoreticalGaplessness from disorder and quantum geometry in gapped superconductorsOmri Lesser, Sagnik Banerjee, Xuepeng Wang, Jaewon Kim et al.arXiv·2026·10.1073/pnas.1309394110·arXiv:2505.15891AbstractQuantum geometry can strongly influence the low-energy properties of gapped superconductors in the presence of disorder. The paper develops a low-energy Bogoliubov–de Gennes description and a microscopic square-lattice model with tunable quantum geometry and disorder in the pairing interaction. It shows that the Fubini-Study metric enhances the localization length and hybridization of Andreev bound states at disorder-induced π-junctions, and reports numerical results for localization length, inverse participation ratio, superfluid stiffness, and spectral functions as a function of quantum geometry.Read more
