论文摘要

在规范量子重力的背景下,我们考虑了重力波函数非标准表达对通货膨胀扰动进化的影响。这种表达及其效应可能是由于(几乎恒定)的充气电位突然变化而产生的。最终的原始光谱,直到领先顺序,在短波长状态下受到影响,在短波长状态下,在标准的半经典结果上叠加了具有不可忽视的幅度的振荡行为。此外,一种新颖的非扰动方法用于研究进化。最后,简化的应用程序得到了充分说明和评论。

In the context of canonical quantum gravity, we consider the effects of a non-standard expression for the gravitational wave function on the evolution of inflationary perturbations. Such an expression and its effects may be generated by a sudden variation in the (nearly constant) inflaton potential. The resulting primordial spectra, up to the leading order, are affected in the short and in the long wavelength regime, where an oscillatory behavior with a non-negligible amplitude is superimposed on the standard semiclassical result. Moreover, a novel, non-perturbative, approach is used to study the evolution. Finally, a simplified application is fully illustrated and commented.
