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…

Non-adiabatic cosmological production of ultra-light Dark Matter
Nathan Herring, Daniel Boyanovsky, Andrew R. Zentner
We study the non-adiabatic cosmological production of ultra light dark matter (ULDM) under a minimal set of assumptions: a free ultra light real scalar as a spectator field in its…
