“…Another example is the proof of the area law for the Wilson loop in a simple lattice gauge theory [GGM78]. One can also mention the microscopic theory of phase coexistence, see [MS67], [GMM73], [Ga72a] and developed in great detail later, see for instance [Mi95]. Problems on large deviations in the theory of Gibbs states can also be solved quite easily by the method, see [GMM78], [GLM02].…”
