Description
The SYK model and its generalizations provide a rare analytically solvable window into many-body quantum chaos. In this talk, we will study a spatially local generalization of the model, the SYK lattice. We will extend it onto the Schwinger–Keldysh closed-time contour, and perform a long wavelength expansion to arrive at the corresponding local SK EFT. This derivation illustrates how hydrodynamic variables are embedded into the microscopic degrees of freedom, and allows us to compute all transport coefficients for the SYK lattice. Based on arxiv:2604.18675, with Marta Bucca, Mark Mezei and Alexey Milekhin.
