坍缩模型中的暴胀引力波

Inflationary gravitational waves in collapse scheme models

Mauro Mariani, Gabriel R. Bengochea, Gabriel Leon

摘要:

暴胀范式是协和宇宙学模型的重要基石。然而,标准暴胀不能完全解决从早期均匀和各向同性阶段到另一个缺乏与我们现在的宇宙相对应的对称性的阶段的过渡。在以前的工作中,一个自诱导的波函数的崩溃已被建议作为缺少的暴胀成分。大多数关于坍缩假说的分析都只集中在与标量扰动相关的谱的特征上,并且在半经典引力框架内。在这封信中,工作在一个联合的度量物质量子化的通货膨胀,我们计算,第一次,张量功率谱和张量标量比对应的原始引力波的振幅,从考虑一个通用的自诱导坍缩。

英文摘要:

The inflationary paradigm is an important cornerstone of the concordance cosmological model. However, standard inflation cannot fully address the transition from an early homogeneous and isotropic stage, to another one lacking such symmetries corresponding to our present universe. In previous works, a self-induced collapse of the wave function has been suggested as the missing ingredient of inflation. Most of the analysis regarding the collapse hypothesis has been solely focused on the characteristics of the spectrum associated to scalar perturbations, and within a semiclassical gravity framework. In this Letter, working in terms of a joint metric-matter quantization for inflation, we calculate, for the first time, the tensor power spectrum and the tensor-to-scalar ratio corresponding to the amplitude of primordial gravitational waves resulting from considering a generic self-induced collapse.
