Feynman graph — A Feynman graph is a graph suitable to be a Feynman diagram in a particular application of quantum field theory. (The most common use is when each field has quanta (particles) associated with it as the quantum of the electromagnetic field is a… … Wikipedia
Effective action — In quantum field theory, the effective action is a modified expression for the action, which takes into account quantum mechanical corrections, in the following sense: In classical mechanics, the equations of motion can be derived from the action … Wikipedia
Convolution power — In mathematics, the convolution power is the n fold iteration of the convolution with itself. Thus if x is a function on Euclidean space Rd and n is a natural number, then the convolution power is defined by where * denotes the convolution… … Wikipedia

Vertex function — In quantum electrodynamics, the vertex function describes the coupling between a photon and an electron beyond the leading order of perturbation theory. In particular, it is the one particle irreducible correlation function involving the fermion… … Wikipedia
Parity (physics) — Flavour in particle physics Flavour quantum numbers: Isospin: I or I3 Charm: C Strangeness: S Topness: T Bottomness: B′ Related quantum numbers: Baryon number: B Lepton number: L Weak isospin: T or T3 Electric charge: Q … Wikipedia
Virial coefficient — Virial coefficients B i appear as coefficients in the virial expansion of the pressure of a many particle system in powers of the density. They are characteristic of the interaction potential between the particles and in general depend on the… … Wikipedia
Bohm interpretation — The Bohm interpretation of quantum mechanics, sometimes called Bohmian mechanics, the ontological interpretation, or the causal interpretation, is an interpretation postulated by David Bohm in 1952 as an extension of Louis de Broglie s pilot wave … Wikipedia
Multipole moments — are the coefficients of a series expansion of a potential due to continuous or discrete sources (e.g., an electric charge distribution). A multipole moment usually involves powers (or inverse powers) of the distance to the origin, as well as some … Wikipedia
