论文摘要
最近提出了一种形式主义，以描述非扰动政权中的假疫苗衰减。在这里，我们将其扩展到爱因斯坦重力的存在，并计算出$ λϕ^4 $标量场理论的相应有效势和衰减速率。与通常的扰动衰减率的比较表明，耦合$λ$越高，衰减概率越大。我们得出的结论是，从自我交联耦合的运行中，理论变得薄弱地耦合在红外极限中，这证明了爱因斯坦重力使弱耦合近似变得更加可靠，随着宇宙的冷却。我们对这些结果的未来应用在宇宙学相变，重力波天文学和凝结物质系统中的未来应用。
A formalism to describe the false-vacuum decay in non-perturbative regimes was proposed recently. Here, we extend it to the presence of Einstein gravity and calculate the corresponding effective potential and decay rate for a $λϕ^4$ scalar field theory. A comparison with the usual perturbative decay rate shows that the higher the coupling $λ$, the greater the decay probability. From the running of the self-interaction coupling, we conclude that the theory becomes weakly coupled in the infrared limit, which proves that Einstein gravity made the weak coupling approximation even more reliable as the universe cooled down. We comment on future applications of these results to cosmological phase transitions, gravitational-wave astronomy, and condensed matter systems.
