论文摘要
我们通过定义标量场的有效潜力,然后执行三维数值模拟,从而观察到重力波电波中的任何可能的区别,从而在存在非最小耦合标量场的情况下研究了一阶真空相变。尽管我们对模型的描述具有不断扩展的背景,但在本文中,我们排除了比例因素的贡献,因为我们主要关注过渡初始阶段非微耦合的直接影响。即使在这种情况下,我们发现这种修饰对重力波能密度的功率谱也有明显的影响。
We investigate first-order vacuum phase transitions in the presence of a non-minimally coupled scalar field starting with the coupling effect on the initial dynamics of phase transitions by defining an effective potential for the scalar field and then performing three dimensional numerical simulations to observe any possible distinction in gravitational wave power spectrum. Although we give a description of the model with the expanding background, in this particular paper, we exclude the scale factor contribution since we primarily focus on the immediate impact of the non-minimal coupling at initial phases of the transition. Even in this case we found that this modification has discernible effect on the power spectrum of the gravitational wave energy density.
