Spontaneous Symmetry Breaking and Nambu–Goldstone Bosons in Quantum Many-Body Systems [PDF]
Symmetry, 2010 Spontaneous symmetry breaking is a general principle that constitutes the underlying concept of a vast number of physical phenomena ranging from ferromagnetism and superconductivity in condensed matter physics to the Higgs mechanism in the standard model

Spontaneous Breakings of Chiral Symmetries
Physical Review D, 1970We analyze in detail the spontaneous breakings of chiral $\mathrm{SU}(3)\ensuremath{\bigotimes}\mathrm{SU}(3)$ and $\mathrm{SU}(2)\ensuremath{\bigotimes}\mathrm{SU}(2)$. We determine the directions along which the two groups may break spontaneously.

Spontaneous breaking of topological symmetry
Physical Review Letters, 1992Summary: The spontaneous breaking of topological symmetry induced by a vanishingly small symmetry breaking term is investigated. It is shown that, in the presence of Gribov zero modes, topological theories without smearing terms, which are inequivalent to theories with smearing terms, permit spontaneous symmetry breaking.

Spontaneous breaking of the gauge symmetry
2006We have seen in Chap. 7 that the neutral vector boson fields coupled to the \(SU(2)\) and \(U(1)\) charges appear as linear combinations of the massless photon field and of the \(Z^0\) field; similarly, left-handed quarks with charge \(-1/3\) enter the weak interaction term as linear combinations of the corresponding mass eigenfields. We show here that

Gravitation and Spontaneous Symmetry Breaking
Foundations of Physics, 1986It is pointed out that the Higgs field may be supplanted by an ordinary Klein-Gordon field conformally coupled to the space-time curvature, and with very small, real, rest mass. Provided there is a bare cosmological constant of order of its square mass, this field can induce spontaneous symmetry breaking with a mass scale that can be as large as the ...

CP Nonconservation and Spontaneous Symmetry Breaking
Physics Reports, 1974The observed CP violation is assumed to be due to the spontaneous symmetry-breaking mechanism; the Lagrangian is CP invariant but its particular solution is not. The general classification of such theories when coupled with different unified gauge models of the weak and electromagnetic interactions is given.

We consider in here the spontaneous generation of chirality from achiral phases in several scenarios. The crystallization of conglomerates, which entails the formation of one chiral crystal phase out of an achiral, or rapidly racemizing, homogeneous phase, is one of them.

Systems with Spontaneous Symmetry-Breaking
1987Many physical systems, seemingly quite different from one another, turn out to be susceptible to investigation by certain topological methods. The phenomenon that unifies such physically different systems as liquid crystals, magnetism, and superfluid helium, is called spontaneous symmetry breaking.

Abstract In this chapter we present the phenomenon of spontaneous symmetry breaking (SSB). This is a mechanism of great importance both in particle physics and in condensed matter physics. Its generality and importance stem from the fact that it deals with how a symmetry of the action in QFT (or of the Hamiltonian in a statistical system)
