Hamiltonian Monte Carlo simulation of the two-dimensional Wess-Zumino model

Numerical simulations of lattice field theories are usually performed in the Lagrangian formulation. The alternative approach of the Hamiltonian formulation [1] has received very little attention so far. Nonetheless, we think there are very good reasons to develop numerical simulation techniques for the Hamiltonian approach: powerful many-body techniques are available [2], which allow the direct computation of the vacuum wave function properties; fermions are implemented directly and need not be integrated out; property like the mass spectrum are more immediate. A check of universality between the Lagrangian and the Hamiltonian formalism would also be very welcome.
