тАЬCosmic Inflation, Birefringence and BaryogenesisтАЭ

Abstract: Cosmic birefringence opens up the possiblity that the baryon asymmetry can be generated during the inflationary epoch either from the gauge or gravitational sector. In this talk, I show birefringent gauge or gravitional modes generated during inflation can lead to a self consistent, with minimal finetuning, baryogenesis mechanism. I discuss future challenges and observational probes, specifically placed on the reheating epoch.
