The localisation of low-temperature interfaces in $d$ dimensional Ising model

Probability 2019-06-24 v2

Abstract

We study the Ising model in a box Λ\Lambda in Zd\mathbb{Z}^d (not necessarily parallel to the directions of the lattice) with Dobrushin boundary conditions at low temperature. We couple the spin configuration with the configurations under ++ and - boundary conditions and we define the interface as the edges whose endpoints have the same spins in the ++ and - configurations but different spins with the Dobrushin boundary conditions. We prove that, inside the box Λ\Lambda, the interface is localized within a distance of order ln2Λ\ln^2|\Lambda| of the set of the edges which are connected to the top by a ++ path and connected to the bottom by a - path.
