论文摘要

我们研究了相关的暗能量的互动性玻色 - 因斯坦气体模型中原始引力波的演变和功率谱,因为它解决了巧合问题。该模型应用于辐射,物质和黑暗能源支配阶段。该模型引入了与辐射介质过渡相关的比例因子,该降低因素会影响引力光谱。我们专注于自由参数对重力波振幅及其功率光谱斜率的影响。对于拟合哈勃定律的一组参数,我们表明该模型的深色 - 物能密度的参数会对此类波浪产生明显影响,而其他波则产生了无法区分的效果。讨论了在当前和将来的测量下检测此类波的可行性。

We study the evolution and power spectrum of primordial gravitational waves in the interactive Bose-Einstein gas model for dark energy, relevant, as it addresses the coincidence problem. The model is applied in the radiation, matter and dark-energy domination stages. The model introduces a scale factor associated to the radiation-matter transition which influences the gravitational spectrum. We focus on the impact of the free parameters on both the gravitational waves amplitude and its power-spectrum slope. For sets of parameters fitting Hubble's law, we show that the model's parameter for today's dark-matter energy density has a noticeable impact on such waves, while the others produce an indistinguishable effect. The feasibility of detecting such waves under present and future measurements is discussed.
