标题： Quantum corrections to the primordial tensor spectrum: Open EFTs & Markovian decoupling of UV modes

摘要： 原始功率谱的微扰量子修正对于检验膨胀作为有效场论的稳健性和有效性范围非常重要。尽管通过圈修正已经对此进行了广泛研究（在一定程度上也研究了张量谱），我们采用开放量子系统方法来处理该问题。 具体来说，我们计算由于（三次）张量相互作用单独引起的原始引力波谱的一阶修正。 我们表明，我们的结果仅在严格的马尔可夫极限下与标准圈修正的预期相符，因此，建立了一种系统的方法在未来放松这一近似，这对于引力系统通常是必要的。 显示英文摘要

摘要： Perturbative quantum corrections to primordial power spectra are important for testing the robustness and the regime of validity of inflation as an effective field theory. Although this has been done extensively for the density power spectrum (and, to some extent, for the tensor spectrum) using loop corrections, we do so in an open quantum system approach to the problem. Specifically, we calculate the first order corrections to the primordial gravitational wave spectrum due to (cubic) tensor interactions alone. We show that our results match expectations from standard loop corrections only in the strict Markovian limit, and therefore, establish a systematic way to relax this approximation in the future, as is generally necessary for gravitational systems.
