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.

沼泽地、跨普朗克审查和通货膨胀的微调问题：隧道波函数拯救

跨普朗克审查猜想意味着，由于膨胀的规模非常小，膨胀的单场模型需要对初始条件进行极端微调。在这项工作中，我们展示了量子宇宙学提议——即隧道波函数——如何自然地提供必要的初始条件，而不需要这样的微调。更一般地说，我们展示了隧道波函数如何为山顶膨胀模型提供合适的初始条件，后者通常受到沼泽地约束的青睐。
