DESCRIPTION:Title: Probing small-scale primordial features with the Stocha
 stic Gravitational Wave Background\n\nSpeaker: Sébastien Renaux-Petel (In
 stitut d’Astrophysique de Paris)\n\nZoom Meeting: 992 4823 1043 (Pass
 word: 455095)\n\nAbstract: Features of the primordial density fluctuation
 s power spectrum are theoretically extremely motivated from embeddings of 
 inflation in high-energy physics\, and detecting them would provide a uniq
 ue insight into the physics of the early universe. To date\, observational
  constraints and prospects for detection have concentrated on the CMB and 
 Large Scale Structure surveys\, butI will explain in this talk how the sto
 chastic gravitational wave background (SGWB) offers a new way to probe pri
 mordial features on small scales. In particular\, I will show how sharp an
 d resonant features give rise to specific oscillatory patterns in the freq
 uency profile of the SGWB\, which can be detected by the upcoming generati
 on of gravitational wave detectors like LISA.\n\nhttps://indico.itp.ac.cn/
