Superconductivity of incoherent electrons in the Yukawa Sachdev-Ye-Kitaev model

Laura Classen et al.

Summary: In a model of N fermions coupled to M bosons by a complex Yukawa coupling, the interplay between non-Fermi liquid and superconductivity in a strongly coupled, critical environment is explored. The phase diagram is analyzed for complex interaction and N/M ratio, with focus on two non-Fermi-liquid regimes. It is shown that the system transitions between these regimes by varying the fermion-boson coupling strength or the ratio MIN, and is unstable to superconductivity below a threshold of time-reversal-symmetry-breaking disorder strength.

Superconducting instabilities in a spinful Sachdev-Ye-Kitaev model

Etienne Lantagne-Hurtubise et al.

Summary: We introduce a spinful variant of the Sachdev-Ye-Kitaev model with an effective time-reversal symmetry, which can be solved exactly in the limit of a large number N of degrees of freedom. At low temperature, its phase diagram includes a compressible non-Fermi liquid and a strongly correlated spin singlet superconductor, separated by a first-order transition.

Phase diagram of the spin-1/2 Yukawa-Sachdev-Ye-Kitaev model: Non-Fermi liquid, insulator, and superconductor

Wei Wang et al.

Summary: The study analyzes the phase diagram of the spin-1/2 Yukawa-Sachdev-Ye-Kitaev model at finite temperatures and with varying fermion density. It shows that in a model with time-reversal symmetry, the quantum phase transition is preempted by a pairing phase. Additionally, the first-order quantum phase transition may extend to finite temperatures and terminate at a thermal critical point.

Yukawa-SYK model and self-tuned quantum criticality

Gaopei Pan et al.

Summary: Non-Fermi liquids are strongly interacting gapless fermionic systems without long-lived quasiparticle excitations. The Yukawa-SYK model features self-tuned quantum criticality and shows exotic quantum-critical NFL properties in the Green's function of fermions and bosons. The model can be solved exactly via large-scale quantum Monte Carlo simulation and provides insights into critical Planckian metals and unconventional superconductors.
