Leptogenesis from Gravity Waves in Models of Inflation

A mechanism for creating the observed cosmic matter-antimatter asymmetry will be presented, which satisfies all three Sakharov conditions from one common thread, gravitational waves. Lepton number is generated through the gravitational anomaly in the lepton number current. The source term comes from elliptically polarized gravity waves that are produced during inflation if  the inflaton field contains a CP-odd component.
