Stochastic Quantization  

In General
* Idea: Quantum mechanics or quantum field theory is formulated as an equilibrium state of a statistical system coupled to a thermal reservoir in Euclidean space (see, e.g., the Fokker-Planck equation); This can be considered as an independent approach to quantum theory, or as a tool to evaluate (Euclidean) path integrals, with the same physical interpretation; It is used mostly for gauge field theories.
* Remark: The real time t of quantum theory cannot be used as the evolution parameter of the stochastic process, since then one does not get the Schrödinger equation.
