We construct an integrable lattice model of classical interacting spins in discrete space-time. representing a discrete-time analogue of the lattice Landau-Lifshitz ferromagnet with uniaxial anisotropy. As an application we use this explicit discrete symplectic integration scheme to compute the spin Drude weight and diffusion constant as functions of anisotropy and chemical potential.... https://jeepworldes.shop/product-category/mirror-relocation/
