摘要
Stochastic quantization of the O(N) phi(4)-field theory is studied in the broken symmetry phase by a variational approach. The resulting integral equation is solved analytically to any order in 1/N expansion. This method is adapted to fermionic models. In particular, an analytic fermionic toy model is introduced in D = 0 and we argue that the D-dimensional case is directly accessible in this way.
