By virtue of their special properties in coupling to the vacuum of the respective symmetry-broken theory, vanishing momentum ("soft") Goldstone bosons involved in field-theoretic amplitudes make … See more In particle and condensed matter physics, Goldstone bosons or Nambu–Goldstone bosons (NGBs) are bosons that appear necessarily in models exhibiting spontaneous breakdown of continuous symmetries. … See more The principle behind Goldstone's argument is that the ground state is not unique. Normally, by current conservation, the charge operator … See more Nonrelativistic theories A version of Goldstone's theorem also applies to nonrelativistic theories. It essentially states … See more Goldstone's theorem examines a generic continuous symmetry which is spontaneously broken; i.e., its currents are conserved, but the See more Natural • In fluids, the phonon is longitudinal and it is the Goldstone boson of the spontaneously broken Galilean symmetry. In solids, the situation is more … See more There is an arguable loophole in the theorem.
