Primordial Stochastic Gravitational Wave Backgrounds in Multi-field Inflation
Offered By: Erwin Schrödinger International Institute for Mathematics and Physics (ESI) via YouTube
Course Description
Overview
Explore the potential of stochastic gravitational wave backgrounds (SGWB) in multi-field inflation models during this 30-minute talk by Sonia Paban at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into how SGWB could provide crucial information about astrophysical source populations and processes, including insights into the early stages of inflation. Examine the importance of precise predictions for observables like the frequency dependence of the fractional energy density spectrum. Investigate the implications of UV-complete inflationary models predicting an abundance of light scalars and how multi-field inflation models may produce an SGWB detectable by LISA. Analyze the relationship between the frequency profile and the number of fields in these models, gaining a deeper understanding of primordial gravitational wave backgrounds in the context of multi-field inflation.
