Long-range inverse 2-spin correlations in one-dimensional potts lattices Tejero, C. F. Cuesta, J. A. Brito López, Ricardo 536 Inverse two-spin correlation function One-dimensional Potts Model Ising model Lattice model. Termodinámica 2213 Termodinámica The inverse two-spin correlation function of a one-dimensional three-state Potts lattice with constant nearest-neighbor interactions in a uniform external field is derived exactly. It is shown that the external field induces long-range correlations. The inverse two-spin correlation function decays in a monotonie exponential fashion for a ferromagnetic lattice, while it decays in an oscillatory exponential fashion for an antiferromagnetic lattice. With no external field the inverse two-spin correlation function has a finite range equal to that of the interactions.
