[en] The authors investigate how string vacua arise from N = 2 superconformal models. In particular, the authors discuss how Landau-Ginzburg models with appropriate central charge can be orbifoldized to construct string vacua. The authors develop techniques to compute the degeneracy and quantum numbers of the ground states of the LG Models in the twisted sectors, even for the cases where the underlying LG model is mot exactly solvable. This allows them to compute some interesting physical quantities such as the number of generations and anti-generations in the simplest compactification scenarios. The results agree with explicit computations in the cases where LG model is exactly solvable
