Abstract
This paper considers a type of generalized large SYK models which include multi-body interactions between Majorana fermions. We derive an effective action in the limit of large and large (with small), and find a universal expression for thermodynamical quantities. We also consider the chaos exponent using the retarded kernel method and find an efficient way to calculate the Lyapunov exponent for generalized large SYK models numerically.
