Arthur Hutsalyuk (ELTE Elm. Fiz. Tanszék):
Finite temperature spin diffusion in the Hubbard model in the strong
coupling limit

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.
