论文摘要
最近，由于拟议的Swampland标准，旨在逃避弦乐景观内的任何（meta-）稳定的Sitter构造，通货膨胀宇宙学正在面临生存危机。已经意识到，除非在某些非标准情况下实现的通货膨胀模型，例如温暖的通货膨胀或Braneworld情况，否则单场慢速滚动通货膨胀与Swampland标准不一致。在\ Cite {Dimopoulos}中，Dimopoulos和Owen在标准的冷通货膨胀情况下引入了一种新的通货膨胀模型，称为电力法高原通胀。但是，要在与观察一致的标准情况下实现此模型，他们必须引入热气膨胀阶段。在本文中，我们在Braneworld场景中分析了该模型，以表明，对于定义模型类别的参数，可以在观察方面具有一致的功率定律高原，而无需任何热通货膨胀阶段。我们还表明，为了正确选择模型参数，可以轻松满足Swampland Criterion。此外，对于潜在的特定选择，也可以满足最近提出的Trans-Planckian审查制度的猜想。
In the recent time, inflationary cosmology is facing an existential crisis due to the proposed Swampland criterion which aims to evade any (meta-)stable de Sitter construction within the String landscape. It is been realised that a single field slow roll inflation is inconsistent with the Swampland criterion unless the inflationary model in realised in some non standard scenario such as Warm inflation or the Braneworld scenario. In \cite{Dimopoulos}, Dimopoulos and Owen introduced a new class of model of inflation dubbed as the power law plateau inflation in the standard cold inflationary scenario. But to realise this model in the standard scenario consistent with observation, they had to introduce a phase of thermal inflation. In this paper we have analysed this model in the braneworld scenario to show that for some choice of the parameters defining the model class, one can have an observationally consistent power law plateau without any phase of thermal inflation. We have also shown that, for the correct choice of model parameters, one can easily satisfy the Swampland criterion. Besides, for a particular choice of the potential one can also satisfy the recently proposed Trans-Planckian Censorship Conjecture.
