The Phase Separation Line in the Two-Dimensional Ising Model
Communication in Mathematical Physics, 27, 103--136, 1972.
Abstract: We prove that, at low temperature, the line of separation between the two pure phases shows large fluctuations in shape. This implies the translation invariance of the correlation functions associated with some non translation invariant boundary conditions and should be a peculiarity of the dimensionality of the model.
