00925njm 22002777a 4500 dc Tejero, C. F. author Cuesta, J. A. author Brito López, Ricardo author 1989 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. 0022-4715 10.1007/BF01044229 https://hdl.handle.net/20.500.14352/58667 http://dx.doi.org/10.1007/BF01044229 http://link.springer.com/ Long-range inverse 2-spin correlations in one-dimensional potts lattices
