The two-dimensional Coulomb gas can be used as a framework for describing fields in minimal models. This comes from the similarity of the two-point correlation function of the free boson φ φ , ⟨ ⟨ φ φ ( z , z ¯ ¯ ) φ φ ( w , w ¯ ¯ ) ⟩ ⟩ = − − log ⁡ ⁡ | z − − w | 2 to the electric potential energy between two unit charges in two dimensions.
