Intrinsic superconducting instabilities of a solvable model for an incoherent metal
Debanjan Chowdhury, Erez Berg
Abstract
This paper reveals the unconventional nature of pairing instabilities out of a non-Fermi liquid metal at strong coupling in a family of exactly solvable Sachdev-Ye-Kitaev models that goes beyond the conventional BCS framework, but that still shows surprising similarities with the BCS-Eliashber theory theory.
