预测自然费米子再加热和暗能量占75%的新暴胀模型

New Model of Inflation that Predicts Natural Fermion Re-heating and a Dark-Energy energy-fraction of 75%

Patrick Lee Nash

摘要:

我们研究了耦合爱因斯坦,电磁(与源)和第二重力\cite{Nash2010}方程的模型宇宙学解决方案,采用了一个平坦的宇宙弗里德曼- \text{Lema{\^ ı}tre} -罗伯逊-沃克(FLRW)线元素的比例因子$a = a(t)$ [共动坐标]的爱因斯坦部门。耦合场方程的解产生比例因子$a(t)$,其最初以指数方式变化$a(t) = a(0) {e}^{H t}$。指数增长一直持续到同动时间接近膨胀的终点,然后$a(t)$迅速转变为对$t$的幂律依赖。在这个模型中,伴随着从暴胀的过渡,自然地重新加热和激发标准模型的自由度,特别是带电的夸克和轻子。没有标量暴胀子场,或慢滚势的引入,以实现这些效果。这一模式在两个方面值得注意。通过光子波函数的推广,证明了二次引力\emph{unit}场$\mathbf{u}$和暗能量之间的合理联系,并概述了将宇宙总能量的75%分配给暗能量的情景。其次,我们推测,如果(量子化)单位场可以从基态激发出来,则可以观察到光子的实验可检测的子结构。

英文摘要:

We study a model cosmological solution of the coupled Einstein, electromagnetic (with source) and second-gravity \cite{Nash2010} equations that employs a flat universe Friedmann-\text{Lema{\^ ı}tre}-Robertson-Walker (FLRW) line element with scale factor $a = a(t)$ [comoving coordinates] for the Einstein sector. The solution of the coupled field equations yields a scale factor $a(t)$ that initially varies exponentially $a(t) = a(0) {e}^{H t}$. Exponential growth continues until the comoving time approaches the end of inflation, then $a(t)$ rapidly transitions to a power law dependence on $t$. Concomitant with the transition from inflation in this model is a natural re-heating and excitation of Standard Model degrees of freedom, and in particular of electrically charged quarks and leptons. No scalar inflaton field, or slow-roll potential is introduced to achieve these effects. This model is noteworthy in two respects. A plausible connection between the second-gravity \emph{unit} field $\mathbf{u}$ and Dark Energy, through the generalization of the photon wave function, is demonstrated, and a scenario is outlined that allocates a 75% fraction of the total energy of the Universe to Dark Energy. Secondly, we conjecture that an experimentally detectable substructure of the of the photon can be observed if the (quantized) unit field can be excited out of its ground state.
