Critical phenomena of thick branes in warped spacetimes
Antonio Campos
We have investigated the effects of a generic bulk first-order phase transition on thick Minkowski branes in warped geometries. As occurs in Euclidean space, when the system is bro…
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…
Bulk effects in the cosmological dynamics of brane-world scenarios
Antonio Campos, Carlos F. Sopuerta
In this paper we deal with the cosmological dynamics of Randall-Sundrum brane-world type scenarios in which the five-dimensional Weyl tensor has a non-vanishing projection onto the…
Dynamics of Cosmological Models in the Brane-world Scenario
Antonio Campos, Carlos F. Sopuerta
We present the results of a systematic investigation of the qualitative behaviour of the Friedmann-Lemaitre-Robertson-Walker (FLRW) and Bianchi I and V cosmological models in Randa…
Evolution of Cosmological Models in the Brane-world Scenario
Antonio Campos, Carlos F. Sopuerta
In this work we consider Randall-Sundrum brane-world type scenarios, in which the spacetime is described by a five-dimensional manifold with matter fields confined in a domain wall…
