φ4 in three dimensions. A stochastic slave equation simulation
Abstract
Differentiating the Langevin equation successively with respect to a source field gives a set of slave equations, which describe the evolution of the estimators of connected Green's functions of arbitrary order. φ4 in three dimensions, a non-trivial theory, is simulated using this method and the approach to the continuum is observed.
