|Numerical simulation based on lattice regularization is a powerful non-
perturbative tool for the quantum field theory. Thanks to recent development
of formulation, now simulation of supersymmetric gauge theory is possible.
In this seminar, I will present some results for 2-dimensional N=(2,2) super
Yang-Mills theory. First we confirm that the supersymmetry, which is broken
at finite lattice spacing, is in fact realized in the continuum limit. And then we
measure the vacuum energy, which is important to observe spontaneous SUSY
breaking if any in this system.
