论文摘要
Higgs领域是充气量的有吸引力的候选人，因为它是观察确认的基本标量场。重要的是，它可以由最通用的骨质量标量电位进行建模。但是，如果经典的希格斯电势用于通货膨胀模型，则可以通过详细观察到宇宙微波背景来排除它。在这里，将非绝热量子动力学在宇宙学模型中的新应用显示出导致多场HigGS样潜力，这与观察到略带红倾斜的功率谱和较小的张量量表的比例一致，而无需非标准成分。这些方法自然会导致通货膨胀开始时的新作用，从而通过应用不确定性关系来估算早期宇宙中初始量子波动来避免常见的微调问题。此外，由于派生的多场相互作用，通货膨胀顺利结束。
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.
