We propose a modification of the Natural Inflation potential in such a way that the spontaneous symmetry breaking scale f can take values less than one (in Planck units). The proposed potential seems simple enough, however, its consequences are difficult to calculate analytically. Therefore, we illustrate the feasibility of the model by considering some numerical examples that easily satisfy the conditions imposed on the observables \(n_s\) and r by the most recent observations, while at the same time maintaining the number of e-folds during the inflationary epoch within the expected range.

受自然通货膨胀启发的模型

我们建议对自然膨胀势进行修改，以使自发对称破坏尺度f可以取小于 1 的值（以普朗克单位表示）。所提出的潜力似乎很简单，然而，其后果难以分析计算。因此，我们通过考虑一些数值示例来说明模型的可行性，这些示例很容易满足最近观察施加于可观察量\(n_s\)和r的条件，同时保持在通胀时期在预期范围内。
