  At an extremely low-energy scale, it is believed that the two-dimensional
$\mathcal{N}=2$ Wess--Zumino model becomes an $\mathcal{N}=2$ 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
$A$-type minimal model. All our results show a coherence picture being
consistent with the conjectured LG/SCFT correspondence.
