Non-BCS behavior of the pairing susceptibility near the onset of superconductivity in a quantum-critical metal

A Abanov, SS Zhang, AV Chubukov - Physical Review B, 2025 - APS
We analyze the dynamical pairing susceptibility χ pp (ω m) at T= 0 in a quantum-critical
metal, where superconductivity emerges out of a non-Fermi-liquid ground state once the …

[PDF][PDF] Magnetic impurities in a strongly coupled superconductor

S Awelewa, M Dzero - arxiv preprint arxiv:2412.03646, 2024 - scipost.org
We revisit certain aspects of a problem concerning the influence of carrier scattering induced
by magnetic impurities in metals on their superconducting properties. Superconductivity is …
