Perturbed Sachdev-Ye-Kitaev model: a polaron in the hyperbolic plane

A. V. Lunkin, A. Yu. Kitaev, M. V. Feigel'man

We study the SYK $_{4}$ model with a weak SYK $_{2}$ term of magnitude $Γ$ beyond the simplest perturbative limit considered previously. For intermediate values of the perturbation stren…
