Description
We study the lattice N=1 Wess-Zumino model in two dimensions and we construct a sequence ρ(L) of exact lower bounds on its ground-state energy density ρ, converging to ρ in the limit L→∞. The bounds ρ(L) can be computed numerically on a finite lattice with L sites and can be exploited to discuss dynamical symmetry breaking. The transition point is determined and compared with recent results based on large-scale Green function Monte Carlo simulations with good agreement
