论文摘要
跨普兰克审查制度的猜想意味着，由于通货膨胀非常低的规模，通货膨胀的单场模型需要对初始条件进行极端的微调。在这项工作中，我们展示了量子宇宙学的建议（即隧道波函数）如何自然地提供必要的初始条件而无需进行此类微调。更普遍地，我们展示了如何为山顶通货膨胀模型提供合适的初始条件，而后者通常受到Swampland限制的优选。
The trans-Planckian censorship conjecture implies that single-field models of inflation require an extreme fine-tuning of the initial conditions due to the very low-scale of inflation. In this work, we show how a quantum cosmological proposal -- namely the tunneling wavefunction -- naturally provides the necessary initial conditions without requiring such fine-tunings. More generally, we show how the tunneling wavefunction can provide suitable initial conditions for hilltop inflation models, the latter being typically preferred by the swampland constraints.
