Inflation as a spontaneous symmetry breaking of Weyl symmetry

Sonoluminescence as Spontaneous Symmetry Breaking

Although sonoluminescence was discovered in 1933, sofar the phenomenon has not been properly explained. In this paper we interpret this phenonmenon as spontaneous symmetry breaking. First, the single bubble sonoluminescence (SBSL) is considered. The mechanism here has been confirmed to be broken spherical symmetry by the work of D F Gaitan et al and Dam J S et al. In this paper we extend this t...

Nonperturbative Spontaneous Symmetry Breaking

One of the most astonishing results of quantum field theory is spontaneous symmetry breaking. One can say that it is the situation when something arises from the quantization. This means that on the quantum level one has something that was not present on the classical level. Coleman and Weinberg [1] write : “ . . . higher-order effects may qualitatively change the character of a physical theory...

THE FRANK KINETIC MODEL FOR SPONTANEOUS CHIRAL SYMMETRY BREAKING WITH VARIABLE CONCENTRATION OF THE ACHIRAL SUBSTRATE

This paper considers the possibility of spontaneous transition of aracemic mixture (composed of equal amounts of two enantiomeric species, say L and D) into a monochiral state (in which only one enantiomer, say L, is present). Transitions of this kind have been recently experimentally observed. A plausible approach to this phenomenon is a model put forward by Frank, based on simple laws of ...

Mass-Generation by Weyl-Symmetry Breaking

A massless electroweak theory for leptons is formulated in a Weyl space, W4, yielding a Weyl invariant dynamics of a scalar field φ, chiral Dirac fermion fields ψL and ψR, and the gauge fields κμ, Aμ, Zμ,Wμ and W † μ allowing for conformal rescalings of the metric gμν and all fields with nonvanishing Weyl weight together with the corresponding transformations of the Weyl vector fields, κμ, repr...
