但丁的地狱
Dante's Inferno
摘要：
我们提出了一个简单的两个领域的通货膨胀模型，并展示了如何将其嵌入弦论作为一个简单的推广轴子monodromy模型。从现象学上讲，这些预言相当于混沌暴胀的预言，特别是包括了可观测到的大张量模。整个高尺度大场暴胀动力学发生在一个场空间区域内，该区域的直径是参数化的次普朗克，因此提高了我们控制量子校正和实现慢卷暴胀的能力。
英文摘要：
We present a simple two-field model of inflation and show how to embed it in string theory as a straightforward generalization of axion monodromy models. Phenomenologically, the predictions are equivalent to those of chaotic inflation, and in particular include observably large tensor modes. The whole high-scale large-field inflationary dynamics takes place within a region of field space that is parametrically subplanckian in diameter, hence improving our ability to control quantum corrections and achieve slow-roll inflation.
