Title |
Vorticity from Isocurvature in the Early Universe | |||||

Abstract |
Vorticity is ubiquitous in nature however, to date, studies of vorticity in cosmology and the early universe have been quite rare. In this talk, I consider vorticity generation from scalar cosmological perturbations of a perfect fluid system. I show that, at second order in perturbation theory, vorticity is sourced by a coupling between energy density and entropy gradients, thus extending a well-known feature of classical fluid dynamics to a relativistic cosmological framework. This induced vorticity, sourced by isocurvature perturbations, may prove useful in the future as an additional discriminator between inflationary models. |
