Goldstone modes (also known as Nambu-Goldstone bosons)[1] [2] arise from Goldstone's conjecture; that if there is continuous symmetry transformation under which the Lagrangian is invariant, then either the vacuum state is also invariant under the transformation, or there must exist spinless particles of zero mass.
