Superconducting instabilities in spinful SYK models

ORAL

Abstract

In this talk I will introduce a solvable toy model for correlated superconductivity in 0+1 dimensions: a spinful generalization of the Sachdev-Ye-Kitaev model with time-reversal invariant interactions. Its phase diagram includes a correlated superconducting phase that emerges out of a gapless non-Fermi liquid through the spontaneous breaking of the system's global U(1) symmetry. I will then discuss lattice constructions of higher-dimensional superconducting phases based on such spinful SYK models
