Preheating in Quintessential Inflation
A. H. Campos, H. C. Reis, R. Rosenfeld
We perform a numerical study of the preheating mechanism of particle production in models of quintessential inflation and compare it with the usual gravitational production mechani…

Bounds on Direct Couplings of Superheavy Metastable Particles to the Inflaton Field from Ultra High Energy Cosmic Ray Events
A. H. Campos, L. L. Lengruber, H. C. Reis +2
Top-down models for the origin of ultra high energy cosmic rays (UHECR's) propose that these events are the decay products of relic superheavy metastable particles, usually called…

Non-equilibrium dynamics of a thermal plasma in a gravitational field
Antonio Campos, B. L. Hu
We introduce functional methods to study the non-equilibrium dynamics of a quantum massless scalar field at finite temperature in a gravitational field. We calculate the Close Time…
