摘要

我们考虑了在爱因斯坦-高斯-波内特宇宙学的致密化情景中标量场的动力学。结果表明，如果场与曲率的耦合是非最小的，那么它在某些条件下的渐近值可能会偏离其势能的最小值。这意味着由于额外维度的影响，具有（\lambda \phi ^4\）势的标量场可以从（\phi =0\）稳定点稳定下来，这意味着在这样的系统中会发生有效的对称性破缺。

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 influence of extra dimensions a scalar field with \(\lambda \phi ^4\) potential can stabilise away from \(\phi =0\) stable point which means an effective symmetry breaking occurs in such a system.
