论文摘要
对原始功率光谱的摄取量子校正对于测试通货膨胀有效性的鲁棒性和作为有效的野外理论的有效性很重要。尽管使用环校正的密度功率谱（在某种程度上，对于张量频谱）进行了广泛的操作，但我们以开放的量子系统方法来解决问题。具体而言，我们仅由于（立方）张量相互作用而计算对原始重力波谱的一阶校正。我们表明，我们的结果仅在严格的马尔可夫限制中与标准循环校正相匹配，因此，将来建立了一种放宽这种近似值的系统方法，这对于重力系统通常是必需的。
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.
