Abstract:
We study the Euclidean sine-Gordon field theory on the plane with β > 16π/3 and an interaction density confined to a finite square. For β= 4 π we construct correlation functions for the field : sin φ \colon; and show that they are equal to the pseudoscalar ―ψΓψ correlation functions for a free fermion theory with mass term confined to the finite square.
