从薄畴壁到厚畴壁:$φ^8$模型的一个例子

From thin to thick domain walls: An example of the $φ^8$ model

Petr A. Blinov, Vakhid A. Gani, Aliakbar Moradi Marjaneh

摘要:

我们证明了对于$(1+1)$维$φ^8$模型的某些参数值,可以从多项式方程中找到扭结解。对于某些选定的参数值,我们给出了模型所有拓扑扇区中扭结的显式公式。基于所得到的代数方程,我们表明,在一个特殊的限制情况下,扭结与幂律渐近出现在模型中,描述,特别是厚域壁。这类天体可能是现代宇宙学感兴趣的对象。

英文摘要:

We demonstrate that for some certain values of parameters of the $(1+1)$-dimensional $φ^8$ model, the kink solutions can be found from polynomial equations. For some selected values of the parameters we give the explicit formulas for the kinks in all topological sectors of the model. Based on the obtained algebraic equations, we show that in a special limiting case, kinks with power-law asymptotics arise in the model, describing, in particular, thick domain walls. Objects of this kind could be of interest for modern cosmology.
