Interaction rates in cosmology: heavy particle production and scattering
Mudit Rai, Daniel Boyanovsky
We study transition rates and cross sections from first principles in a spatially flat radiation dominated cosmology. We consider a model of scalar particles to study scattering an…

On the origin of entropy of gravitationally produced dark matter: the entanglement entropy
Mudit Rai, Daniel Boyanovsky
We study the emergence of entropy in gravitational production of dark matter particles, ultra light scalars minimally coupled to gravity and heavier fermions, from inflation to rad…

Gravitational production of nearly thermal fermionic Dark Matter
Nathan Herring, Daniel Boyanovsky
We consider the cosmological production of fermionic dark matter during inflation and a post-inflationary radiation dominated era. This fermion \emph{only interacts gravitationally…
