Pseudo-Goldstone boson — Pseudo Goldstone bosons arise in a quantum field theory with an approximate symmetry such that if the symmetry were exact, then there would be spontaneous symmetry breaking (SSB) and the consequent formation of Goldstone bosons. The properties of … Wikipedia
Chiral symmetry — In quantum field theory, chiral symmetry is a possible symmetry of the Lagrangian under which the left handed and right handed parts of Dirac fields transform independently. The chiral symmetry transformation can be divided into a component that… … Wikipedia

Goldstone boson — In particle and condensed matter physics, Goldstone bosons or Nambu–Goldstone bosons are bosons that appear necessarily in models exhibiting spontaneous breakdown of continuous symmetries (cf. spontaneously broken symmetry). They were discovered… … Wikipedia
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
Electro-gyration — The electrogyration effect is the spatial dispersion phenomenon, that consists in the change of optical activity (gyration) of crystals by a constant or time varying electric field. Being a spatial dispersion effect, the induced optical activity… … Wikipedia
