SUMMARY:Amplification of Primordial Perturbations from the Rise or Fall of the Inflaton
DESCRIPTION:\nAPEC Seminar (Astronomy – Particle Physics – Experimental Physics – Cosmology)\n\n\n\nSpeaker:Keisuke Inomata (U Chicago)Title:Amplification of Primordial Perturbations from the Rise or Fall of the InflatonDate (JST):Thu, Jan 06, 2022, 11:00 – 12:00Place:Zoom, please contact IPMU for zoom information. Abstract:The next generation of cosmic microwave background, gravitational wave, and large scale structure, experiments will provide an unprecedented opportunity to probe the primordial power spectrum on small scales. An exciting possibility for what lurks on small scales is a sharp rise in the primordial power spectrum: This can lead to the formation of primordial black holes, providing a dark matter candidate or the black holes observed by the LIGO-Virgo collaboration. In this work we develop a mechanism for the amplification of the small-scale primordial power spectrum, in the context of single-field inflation with a step-like feature in the inflaton potential. Specifically, we consider both the upward and the downward step in the potential. This talk will be based on our papers, arXiv:2104.03972, 2110.14641.\n
