In this paper, we develop a detailed analysis of critical prewetting in the context of the two-dimensional Ising model. Namely, we consider a two-dimensional nearest-neighbor Ising model in a rectangular box with a boundary condition inducing the coexistence of the + phase in the bulk and a layer of − phase along the bottom wall. The presence of an external magnetic field of intensity (for some fixed ) makes the layer of − phase unstable. For any , we prove that, under a diffusing scaling by horizontally and vertically, the interface separating the layer of unstable phase from the bulk phase weakly converges to an explicit Ferrari–Spohn diffusion.
