In this talk, I will discuss two-dimensional random field Ising model where the disorder is given by i.i.d. mean zero Gaussian variables with small variance. In particular, I will present a recent joint work with Mateo Wirth on (one notion of) the correlation length, which is the critical size of the box at which the influences to spin magnetization from the boundary conditions and from the...
