Conformal field theory and the Au(110) (1×2)-to-(1×1) phase transition

Abstract
Conformal field theory predicts the scattering line shape from a finite two-dimensional domain at criticality. Experimental results for the Au(110) (1×2)-to-(1×1) phase transition, which is in the Ising universality class, agree well with the conformal prediction. The effects of boundary conditions and a distribution of domain sizes are accounted for.
