Abstract
We use superspace methods to study an SYK-like model with \( \mathcal{N}=2 \) supersymmetry in one dimension, and an analog of this model in two dimensions. We find the four-point function as an expansion in the basis of eigenfunctions of the Casimir of su(1, 1|1). We also find retarded kernels and Lyapunov exponents for both cases.
