论文摘要
我们研究了混合宇宙学$α$吸收器理论中的两阶段通货膨胀制度。由于该模型的吸引力特性，通货膨胀扰动的范围与最新的Planck/Bicep/Keck结果兼容。但是，在较小的尺度下，它可能具有很高的可控宽度和位置的峰值，从而导致大量的原始黑洞（PBH）产生重力波（SGWB）的随机背景。
We investigate the two-stage inflation regime in the theory of hybrid cosmological $α$-attractors. The spectrum of inflationary perturbations is compatible with the latest Planck/BICEP/Keck results, thanks to the attractor properties of the model. However, at smaller scales, it may have a very high peak of controllable width and position, leading to a copious production of primordial black holes (PBH) and generation of a stochastic background of gravitational waves (SGWB).
