Spontaneous symmetry breaking as a result of extra dimensions compactification

We consider dynamics of a scalar field in compactification scenario of Einstein-Gauss-Bonnet cosmology. It is shown that if the field is non-minimally coupled to curvature, its asymptotic value under certain conditions may be shifted from the minimum of its potential. This means that due to influenc...

Zusammenfassung:We consider dynamics of a scalar field in compactification scenario of Einstein-Gauss-Bonnet cosmology. It is shown that if the field is non-minimally coupled to curvature, its asymptotic value under certain conditions may be shifted from the minimum of its potential. This means that due to influence of extra dimensions a scalar field with λ ϕ 4 potential can stabilise away from ϕ = 0 stable point which means an effective symmetry breaking occurs in such a system.
