Action at a distance in classical uniaxial ferromagnetic arrays

Abstract: We examine in detail the theoretical foundations of striking long-range couplings emerging in arrays of fluid cells connected by narrow channels by using a lattice gas (Ising model) description of a system. We present a reexamination of the well known exact determination of the two-point correlation function along the edge of a channel using the transfer matrix technique and a new interpretation is provided. The explicit form of the correlation length is found to grow exponentially with the cross section of th… Show more

“…More interestingly, thanks to calculations based on the exact solution of the planar Ising model, the relation Σ ab ξ b = 1/2 has been proved to be valid for all subcritical temperatures. This result follows as an application of duality [9,38,39]; see also [40].…”
