Spontaneous breaking of topological symmetry

Physical Review Letters, 1992
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 Breakings of Chiral Symmetries

Physical Review D, 1970
We 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 Symmetry-Breaking

1984
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

Spontaneous Symmetry Breaking

Inference: International Review of Science, 2018
Broken symmetries encompass a large number of different phenomena occurring at different scales. Édouard Brézin examines how symmetry has become central to understanding the organization of the universe.

Gravitation and Spontaneous Symmetry Breaking

Foundations of Physics, 1986
It 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 ...

Systems with Spontaneous Symmetry-Breaking [PDF]

open access: possible, 1987
Many 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.

Spontaneous breaking of the gauge symmetry

2006
We 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

Spontaneous Symmetry Breaking

1994
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
