论文摘要
许多骗子的猜想，尤其是跨普兰克的审查制度猜想（TCC）表明，如果存在完全存在，那么de Sitter空间非常不稳定。在本文中，我们在电势上构建了有效的标量滚动理论，这些电势是对短寿命的DS空间链条双重的，这些空间通过一系列非扰动的气泡成核腐烂，从一个脱落到下一个。我们发现，各种滚动标准，包括TCC，弱重力猜想和距离猜想所产生的有效潜力的限制。出乎意料的是，我们发现TCC实质上结合了所有其他元素，并导致了可能的双重有效电位的子类。这些结果略微排除了双重有效理论中永恒通胀的出现。我们讨论了我们观察的一些宇宙学含义。
A number of Swampland conjectures and in particular the Trans-Planckian Censorship Conjecture (TCC) suggest that de Sitter space is highly unstable if it exists at all. In this paper we construct effective theories of scalars rolling on potentials which are dual to a chain of short-lived dS spaces decaying from one to the next through a cascade of non-perturbative nucleation of bubbles. We find constraints on the effective potential resulting from various swampland criteria, including TCC, Weak Gravity Conjecture and Distance Conjecture. Surprisingly we find that TCC essentially incorporates all the other ones, and leads to a subclass of possible dual effective potentials. These results marginally rule out emergence of eternal inflation in the dual effective theory. We discuss some cosmological implications of our observations.
