Popis:	This paper introduces a minimal generalization of the SYK model, which exhibits a superconducting dome. A pseudogap phase, which appears next to the dome, is dominated by the strong quantum fluctuations. The pseudogap-superconductivity transition can be described as a nonlinear synchronization phenomenon, which is captured by a quantum version of the classical Kuramoto model.
