论文摘要
Swampland的猜想引起了人们对宇宙学界的浓厚兴趣。它们已被证明具有广泛的含义,例如对通货膨胀模型,原始黑洞,深色能量的限制。特别是,它们对基于一般相对性宇宙学的单场通货膨胀模型的影响引起了极大的关注。已经证明以通常的形式的Swampland猜想与这类单场模型不相容,或者已证明在这些通货膨胀模型中诱导严重的微调,以使它们与猜想一致。在这项工作中,我们表明,大量的单场通货膨胀模型实际上可以绕过基于GR的宇宙学中通货膨胀范式所面临的问题。我们将精确的解决方案方法用于同一目的的通货膨胀,并展示如何在非标准宇宙学场景中与各种单场通货膨胀模型进行完美的交响曲。
Swampland conjectures have attracted quite some interest in the cosmological community. They have been shown to have wide ranging implications , like constraints on inflationary models, primordial black holes, dark energy to name a few. Particularly, their implications on single field inflationary models in general relativity based cosmology has gathered huge attention. Swampland conjectures in their usual form have been shown to be incompatible with these kind of single field models, or have been shown to induce severe fine tuning in these inflationary models for them to be consistent with the conjectures. In this work, we show that a large class of single field inflationary models can in fact bypass the problems faced by inflationary paradigms in GR Based cosmology. We use the exact solution approach to inflation for the same purpose and show how string theoretic motivations of the swampland conjectures can be in perfect symphony with various single field inflationary models in non-standard cosmological scenarios.
