Analytic conformal bootstrap and Virasoro primary fields in the Ashkin-Teller model

Nikita Nemkov, Sylvain Ribault

We revisit the critical two-dimensional Ashkin-Teller model, i.e. the ${\mathbb{Z}}_2$ orbifold of the compactified free boson CFT at $c=1$. We solve the model on the plane by comput…
