  <dc:description xmlns:ns0="xml" ns0:lang="en">We derive an effective spin Hamiltonian for the one-dimensional half-filled asymmetric  ionic Hubbard model (IHM) with alternating on-site interaction in the limit of strong  repulsion. It is shown that the effective Hamiltonian is that of a spin S = 1/2 anisotropic  XXZ Heisenberg chain with alternating next-nearest-neighbor (NNN) and three-spin  couplings in the presence of a uniform and a staggered magnetic field.</dc:description>
