One mathematical technique that is commonly used in QFT is analytic continuation of the time variable (e.g., Wick rotation). This strategy relates the relativistic QFT model of interest to a non-relativistic model of some type (e.g., in some cases, a classical or quantum statistical mechanical model). Analytic continuation has been successfully used not merely to solve existing QFT models, but as a tool to construct new QFT models. I will offer explanations for the applicability of this mathematical technique and explore what (if anything) its successful application tells us about quantum field theoretic systems.
