广义不确定原理对暴胀参数的影响

Effects of the Generalized Uncertainty Principle on the Inflation Parameters

Kourosh Nozari, Siamak Akhshabi

摘要:

本文从标准和膜世界两个角度研究了广义不确定原理对早期宇宙暴胀动力学的影响。我们选择兰德尔-桑德拉姆II模型作为我们的底层膜世界场景。我们发现,量子引力效应导致的光谱指数,这是不是标度不变。此外,密度波动的幅度通过增加量子引力修正的强度而减小。然而,张量标量比增加纳入这些量子引力效应。我们概述了这些量子引力效应在最近和未来观测中的可能表现。

英文摘要:

We investigate the effects of the generalized uncertainty principle on the inflationary dynamics of the early universe in both standard and braneworld viewpoint. We choose the Randall-Sundrum II model as our underlying braneworld scenario. We find that the quantum gravitational effects lead to a spectral index which is not scale invariant. Also, the amplitude of density fluctuations is reduced by increasing the strength of quantum gravitational corrections. However, the tensor-to-scalar ratio increases by incorporation of these quantum gravity effects. We outline possible manifestations of these quantum gravity effects in the recent and future observations.
