TL;DR
This paper provides an accessible overview of the SYK model, highlighting its significance as a large N quantum field theory with applications in holography and condensed matter physics.
Contribution
It introduces the SYK and tensor models, discusses their properties, and explores their relevance to AdS/CFT correspondence and strange metal phenomena.
Findings
SYK models exhibit near-conformal invariance in the infrared.
Correlation functions can be computed within the SYK framework.
Generalizations of SYK extend its applicability.
Abstract
These notes are a short introduction to the Sachdev-Ye-Kitaev model. We discuss: SYK and tensor models as a new class of large N quantum field theories, the near-conformal invariance in the infrared, the computation of correlation functions, generalizations of SYK, and applications to AdS/CFT and strange metals.
