缓慢演化过程中的绝热谱
Adiabatic Spectra During Slowly Evolving
摘要：
一般情况下，对于单场，曲率扰动的标度不变谱可以由其常模或增模给出。我们证明了在缓慢膨胀或收缩过程中，由其增长模给出的曲率扰动谱可以是尺度不变性的。扰动模态可以自然地扩展到视界外，扰动的幅度与观测结果一致。我们简要讨论了该方案的实现。
英文摘要：
In general, for single field, the scale invariant spectrum of curvature perturbation can be given by either its constant mode or its increasing mode. We show that during slowly expanding or contracting, the spectrum of curvature perturbation given by its increasing mode can be scale invariance. The perturbation mode can be naturally extended out of horizon, and the amplitude of perturbation is consistent with the observations. We briefly discuss the implement of this scenario.
