Title:  Finite temperature spin diffusion in the Hubbard model in the strong
coupling limit

Abstract:

We investigate finite temperature spin transport in one spatial dimension by
considering the spin-spin correlation function of the Hubbard model in the
limiting case of infinitely strong repulsion. We find that in the absence of
bias the transport is diffusive, and derive the spin diffusion constant. Our
approach is based on asymptotic analysis of a Fredholm determinant
representation, which is entirely analytic and free of phenomenological
assumptions of Generalized Hydrodynamics.

Based on arXiv:2301.13840, O. Gamayun et. al.
