Particle decay in post inflationary cosmology
Nathan Herring, Brian Pardo, Daniel Boyanovsky +1
We study scalar particle decay during the radiation and matter dominated epochs of a standard cosmological model. An adiabatic approximation is introduced that is valid for degrees…
Quantum decay in renormalizable field theories: quasiparticle formation, Zeno and anti-Zeno effects
Daniel Boyanovsky
In a renormalizable theory the survival probability of an unstable quantum state features divergences as a consequence of the rapid growth of the density of states with energy. Int…
Imprint of entanglement entropy in the power spectrum of inflationary fluctuations
Daniel Boyanovsky
If the inflaton couples to other degrees of freedom that populate the post-inflationary stage, such coupling modifies the dynamics of the inflaton \emph{during} inflation. We consi…
Information loss in effective field theory: entanglement and thermal entropies
Daniel Boyanovsky
Integrating out high energy degrees of freedom to yield a low energy effective field theory leads to a loss of information with a concomitant increase in entropy. We obtain the eff…
