Critical behavior of the spin correlation function in Ashkin-Teller and Baxter models with a line defect

Carlos Naón

We consider the critical spin-spin correlation function of the Ashkin-Teller and Baxter models. By using path-integral techniques in the continuum description of these models in te…
