An introduction to Double-Scaled SYK

Marta Bucca
Abstract
Sachdev-Ye-Kitaev is an ensemble of quantum mechanical models, consisting of N Majorana fermions with p-body interactions. In the double-scaling limit, we take both N and p to be large, holding p^2/N fixed. In this regime, we can write down an expansion of the partition function using chord diagrams. During this talk I will introduce DSSYK, discuss chord diagrams, and review some key feature
