STRUCTURE CONSTANT OF THE YANG–LEE EDGE SINGULARITY

This paper studies the Yang–Lee singularity of the 2-dimensional Ising model on the cylinder via transfer matrix and finite-size scaling techniques. These techniques enable a measurement of the 2-point and 3-point correlations and a comparison of a measurement of a corresponding universal amplitude with a prediction for the amplitude from the (A4, A1) minimal conformal field theory.
