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.

Testing the effective action approach to bubble nucleation in holography

A two-derivative holographic effective action reproduces critical bubble solutions from the full gravity theory to within a few percent across thin-wall and thick-wall regimes.
