Abstract
In this paper, based on the notion of SYK/AdS duality we explore the effects of Yang-Baxter (YB) deformations on the SYK spectrum at strong coupling. In the first part of our analysis, we explore the consequences of YB deformations through the Kaluza-Klein (KK) reduction on (AdS2)η × (S1)/Z2. It turns out that the YB effects (on the SYK spectrum) starts showing off at quadratic order in 1/J expansion. For the rest of the analysis, we provide an interpretation for the YB deformations in terms of bi-local/collective field excitations of the SYK model. Using large N techniques, we evaluate the effective action upto quadratic order in the fluctuations and estimate 1/J2 corrections to the correlation function at strong coupling.
