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.

As we have seen in Chap. 2, the gauge-invariant theories include massless gauge fields. From the viewpoint of physical applications both massless and massive gauge fields are relevant. Just adding a mass term to the Lagrangian for the gauge field is not allowed since it would lead to the violation of the gauge-invariance of the Lagrangian. Therefore, a

Of the positive attributes of model building with T, rigidity ranks high on the list. The ability to mirror the structural features of our physical reality with flexible mathematics bespeaks more the talents of the model builder than any fundamental connection of the mathematics to reality. To lay claim to such a connection a mathematical idea must, in

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.

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)

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 ...
