岛规则对暴胀和原初扰动的影响

Implication of island for inflation and primordial perturbations

Yun-Song Piao

AI总结:

本文利用岛规则重新审视暴胀e折数的熵约束,证明该约束可能不存在,并指出暴胀后观测到的原初扰动信息通量遵循Page曲线,扰动谱在大尺度上呈现类Page抑制。

摘要:

通常认为,暴胀的e折数必须受其德西特熵约束,否则我们将面临信息悖论。然而,根据计算纠缠熵的岛规则,我们证明这种约束可能不存在,而暴胀后观测者能够探测到的原初扰动模式的信息通量遵循Page曲线。在相应的永恒暴胀时空中,我们的慢滚暴胀补丁似乎伴随着一个邻近的坍缩补丁(最终演化为黑洞),因此其霍金辐射可能正是我们的原初扰动。相应地,我们观测到的扰动谱将在较大尺度上呈现“类Page”的抑制。

英文摘要:

It is usually thought that the efolds number of inflation must be bounded by its de Sitter entropy, otherwise we will have an information paradox. However, in light of the island rule for computing the entanglement entropy, we show that such a bound might be nonexistent, while the information flux of primordial perturbation modes the observer after inflation is able to detect follows a Page curve. In corresponding eternally inflating spacetime, it seems that our slow-roll inflation patch is accompanied with a neighbourly collapsed patch (eventually developing into a black hole) so that its Hawking radiation might be just our primordial perturbations. Accordingly, the perturbation spectrum we observed will present a ``Page-like" suppression at large scale.
