A dynamical inflaton coupled to strongly interacting matter
arXiv:2302.06618 · doi:10.1103/PhysRevLett.130.251001
Abstract
According to the inflationary theory of cosmology, most elementary particles in the current universe were created during a period of reheating after inflation. In this work we self-consistently couple the Einstein-inflaton equations to a strongly coupled quantum field theory (QFT) as described by holography. We show that this leads to an inflating universe, a reheating phase and finally a universe dominated by the QFT in thermal equilibrium.
