The two-dimensional $q$-state clock models exhibit the Berezinskii-Kosterlitz-Thouless (BKT) transition for $q\geq5$ since they are a subset of isotropic XY model. We examine $6$-state model with an anisotropic deformation. Selecting Potts as source deformation, naturally violates discrete rotational symmetry introduce deformation parameter $\alpha$ in interpolating ($\alpha = 1$) and 0$) model...
