Numerical study of ADE-type $\mathcal{N}=2$ Landau--Ginzburg models
Abstract
At an extremely low-energy scale, it is believed that the two-dimensional Wess--Zumino model becomes an superconformal field theory (SCFT). We study this theoretical conjecture of the Landau--Ginzburg (LG) description by numerical simulations based on a supersymmetric-invariant momentum-cutoff regularization. First, from the two-point function of the energy-momentum tensor, we measure the central charge of the ADE minimal models. Second, we develop a method to take the continuum limit, and perform a precision measurement of the scaling dimension in the -type minimal model. All our results show a coherence picture being consistent with the conjectured LG/SCFT correspondence.
