An Investigation of New Methods for Numerical Stochastic Perturbation Theory in $\varphi^4$ Theory
Numerical stochastic perturbation theory is a powerful tool for estimating high-order perturbative expansions in lattice field theory. The standard algorithms based on the Langevin equation, however, suffer from several limitations which in practice restrict the potential of this technique. In this...
