QCD vacuum — The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non perturbative vacuum state, characterized by many non vanishing condensates such as the gluon condensate or the quark condensate. These condensates… … Wikipedia
Vacuum state — In quantum field theory, the vacuum state (also called the vacuum) is the quantum state with the lowest possible energy. Generally, it contains no physical particles. The term zero point field is sometimes used as a synonym for the vacuum state… … Wikipedia
Vacuum permeability — This article is about the magnetic constant. For the analogous electric constant, see vacuum permittivity. Vacuum permeability, permeability of free space, or magnetic constant is an ideal, (baseline) physical constant, which is the value of… … Wikipedia
QCD matter — Quark matter or QCD matter (see QCD) refers to any of a number of theorized phases of matter whose degrees of freedom include quarks and gluons. These theoretical phases would occur at extremely high temperatures and densities, billions of times… … Wikipedia
QCD sum rules — In quantum chromodynamics, the confining and strong coupling nature of the theory means that conventional perturbative techniques often fail to apply. The QCD sum rules are a way of dealing with this. The idea is to work with gauge invariant… … Wikipedia
Stochastic vacuum model — In physics, the stochastic vacuum model is a nonpertubative, phenomenological approach to derive cross section in quantum chromodynamics.It is deemed impossible, to calculate the vacuum averages of gauge invariant quantities in QCD in a closed… … Wikipedia

Fermionic condensate — A fermionic condensate is a superfluid phase formed by fermionic particles at low temperatures. It is closely related to the Bose–Einstein condensate, a superfluid phase formed by bosonic atoms under similar conditions. Unlike the Bose–Einstein… … Wikipedia
Gluon condensate — In Quantum chromodynamics (QCD), the gluon condensate is a non perturbative property of the QCD vacuum which could be partly responsible for giving masses to certain hadrons.If the gluon field tensor is represented as G mu; nu;, thenthe gluon… … Wikipedia
