Dissipation due to Bulk Localized Low-Energy Modes in Strongly Disordered Superconductors
Anton V. Khvalyuk, Mikhail V. Feigel'man
Strongly disordered superconductors (SDSCs) are widely used in qubits, microwave resonators, photon detectors, and other superconducting quantum devices. In SDSC-based devices, coh…

Chiral-helical junctions in screened graphene
Bilal Kousar, Selma Franca, David Perconte +14
Reproducibility and quantization in quantum spin Hall platforms is a persisting challenge, limiting their use in hybrid realizations of topological superconductivity. We report rob…
