Popis:	We consider the probability distribution in a classical semi‐infinite layered ferromagnet with mean‐field interactions and prove that this satisfies a large deviation principle, giving the rate function explicitly. For an analogous quantum system we show that the limiting states are product states, which are completely characterized by the classical mean‐field solutions.
