摘要:

希格斯场是暴胀子的一个有吸引力的候选者,因为它是一个被观测证实的基本标量场。重要的是,它可以用最一般的可重正化标量势来模拟。然而,如果经典的希格斯势被用于暴胀模型中,它被宇宙微波背景的详细观测所排除。在这里,一个新的应用程序的非绝热量子动力学的宇宙学模型,导致多场希格斯粒子的潜力,与观察到的轻微红色倾斜的功率谱和一个小的张量标量比一致,而不需要非标准成分。这些方法自然会在暴胀开始时产生新的效应,通过应用不确定关系来估计早期宇宙中的初始量子涨落,从而规避了常见的微调问题。此外,通货膨胀顺利结束的结果,派生的多场相互作用。

英文摘要:

The Higgs field is an attractive candidate for the inflaton because it is an observationally confirmed fundamental scalar field. Importantly, it can be modeled by the most general renormalizable scalar potential. However, if the classical Higgs potential is used in models of inflation, it is ruled out by detailed observations of the cosmic microwave background. Here, a new application of non-adiabatic quantum dynamics to cosmological models is shown to lead to a multi-field Higgs-like potential, consistent with observations of a slightly red-tilted power spectrum and a small tensor-to-scalar ratio, without requiring non-standard ingredients. These methods naturally lead to novel effects in the beginning of inflation, circumventing common fine-tuning issues by an application of uncertainty relations to estimate the initial quantum fluctuations in the early universe. Moreover, inflation ends smoothly as a consequence of the derived multi-field interactions.
