Ultralight dark matter or dark radiation cosmologically produced from infrared dressing
Daniel Boyanovsky, Mudit Rai, Lisong Chen
Infrared dressing of bosonic or fermionic heavy particles by a cloud of massless particles to which they couple is studied as a possible production mechanism of ultra light dark ma…
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…
Fermionic influence (action) on inflationary fluctuations
Daniel Boyanovsky
Motivated by apparent persistent large scale anomalies in the CMB we study the influence of fermionic degrees of freedom on the dynamics of inflaton fluctuations as a possible sour…
