论文摘要
来自通货膨胀势的原始黑洞（PBH）生产具有拐点，通常很大程度上取决于模型参数的微调。我们在这项工作中提出了一种新型的$α$吸收器通货膨胀，并具有不对称的双极，自然而容易地导致非吸收器膨胀时期，在此期间，PBH生产可以通过较少调整模型参数来保证PBH生产。这种双重通胀可以在未来使用丰富的现象学特征来针对观察数据进行测试：（1）小尺度上的增强曲率扰动承认功率谱中紫外线振荡的独特特征； （2）可以使所产生的PBH的准单色质量质量函数可以使小行星质量质量PBH兼容为主要的暗物质成分，行星质量的PBHs作为OGER ULTRASTORT-TIMENCALE-TIMESSCALE MICLECENTING EVENT，以及Solar-Mass PBHS作为Ligo-virgo事件； （3）可以通过太空中的重力波探测器和脉冲星的定时阵列/平方公里阵列检测到引力波。
The primordial black hole (PBH) productions from the inflationary potential with an inflection point usually rely heavily on the fine-tuning of the model parameters. We propose in this work a new kind of the $α$-attractor inflation with asymmetric double poles that naturally and easily lead to a period of non-attractor inflation, during which the PBH productions are guaranteed with less fine-tuning the model parameters. This double-pole inflation can be tested against the observational data in the future with rich phenomenological signatures: (1) the enhanced curvature perturbations at small scales admit a distinctive feature of ultraviolet oscillations in the power spectrum; (2) the quasi-monochromatic mass function of the produced PBHs can be made compatible to the asteroid-mass PBHs as the dominant dark matter component, the planet-mass PBHs as the OGLE ultrashort-timescale microlensing events, and the solar-mass PBHs as the LIGO-Virgo events; (3) the induced gravitational waves can be detected by the gravitational-wave detectors in space and Pulsar Timing Array/Square Kilometer Array.
