From euclidean field theory to quantum field theory
In order to construct examples for interacting quantum field theory models, the methods of euclidean field theory have turned out to be a powerful tools since they make use of the techniques of classical statistical mechanics. Starting from an appropriate set of euclidean 3⁄4 -point functions (Schwinger distributions), a Wightman theory can be reconstructed by an application of the famous Oster...
متن کاملAxioms for Renormalization in Euclidean Quantum Field Theory
A set of axioms which fix Euclidean renormalizations up to a finite renormalization is proposed. There exists a one to one correspondence between Euclidean renormalizations and renormalizations in Minkowski space-time satisfying Hepp's axioms. No restrictions on masses are imposed.
متن کاملResummation of mass terms in perturbative massless quantum field theory
The neutral massless scalar quantum field Φ in four-dimensional spacetime is considered, which is subject to a simple bilinear self-interaction. Is is well-known from renormalization theory that adding a term of the form −m2 2 Φ to the Lagrangean has the formal effect of shifting the particle mass from the original zero value to m after resummation of all two-leg insertions in the Feynman graph...
متن کاملEuclidean Field Theory
In this review, we consider Euclidean field theory as a formulation of quantum field theory which lives in some Euclidean space, and is expressed in probabilistic terms. Methods arising from Euclidean field theory have been introduced in a very successful way in the study of the concrete models of Constructive Quantum Field Theory. Euclidean field theory was initiated by Schwinger [1] and Nakan...
متن کاملQuantum Correlations in Nuclear Mean Field Theory Through Source Terms
Starting from full quantum field theory, various mean field approaches are derived systematically. With a full consideration of external source dependence , the stationary phase approximation of an action gives a nuclear mean field theory which includes quantum correlation effects (such as particle-hole or ladder diagram) in a simpler way than the Brueckner-Hartree-Fock approach. Implementing f...
