Gaplessness from disorder and quantum geometry in gapped superconductors

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Omri Lesser, Sagnik Banerjee, Xuepeng Wang, Jaewon Kim, Ehud Altman | Summary: It is well known that disorder can induce low-energy Andreev bound states in a sign-changing, but fully gapped, superconductor at $pi-$junctions. Generically, these excitations are localized. Starting from a superconductor with a sign-changing and nodeless […]
