In quantum field theory, the Wightman distributions can be analytically continued to analytic functions in Euclidean space with the domain restricted to the ordered set of points in Euclidean space with no coinciding points. These functions are called the Schwinger functions (named after Julian Schwinger) and they are … See more Here we describe Osterwalder–Schrader (OS) axioms for a Euclidean quantum field theory of a Hermitian scalar field $${\displaystyle \phi (x)}$$, $${\displaystyle x\in \mathbb {R} ^{d}}$$. Note that a typical See more • Wick rotation • Axiomatic quantum field theory • Wightman axioms See more The Osterwalder–Schrader theorem states that Euclidean Schwinger functions which satisfy the above axioms (E0)-(E4) and an additional property … See more Axioms by Glimm and Jaffe An alternative approach to axiomatization of Euclidean correlators is described by Glimm and Jaffe in their book.

The Schwinger–Dyson equations (SDEs) or Dyson–Schwinger equations, named after Julian Schwinger and Freeman Dyson, are general relations between correlation functions in quantum field theories (QFTs). They are also referred to as the Euler–Lagrange equations of quantum field theories, since they are the equations of motion corresponding to the Green's function. They form a set of i… grant execute to stored procedure

WebThe Schwinger effect is a predicted physical phenomenon whereby matter is created by a strong electric field. It is also referred to as the Sauter–Schwinger effect, Schwinger mechanism, or Schwinger pair production. WebDensity matrix renormalization group (DMRG) and Schwinger boson mean field theory (SBMFT) are used to study the behavior of the ground state energy in the integer spin two-dimensional anisotropic J(1 Web12 Apr 2024 · Abstract.
