Existence and Stability of Non-Trivial Scalar Field Configurations in Orbifolded Extra Dimensions
Manuel Toharia, Mark Trodden
We consider the existence and stability of static configurations of a scalar field in a five dimensional spacetime in which the extra spatial dimension is compactified on an $S^1/Z…
Metastable Kinks in the Orbifold
Manuel Toharia, Mark Trodden
We consider static configurations of bulk scalar fields in extra dimensional models in which the fifth dimension is an orbifold. There may exist a finite number of such c…
The Adiabatic Instability on Cosmology's Dark Side
Rachel Bean, Eanna E. Flanagan, Mark Trodden
We consider theories with a nontrivial coupling between the matter and dark energy sectors. We describe a small scale instability that can occur in such models when the coupling is…
Adiabatic instability in coupled dark energy-dark matter models
Rachel Bean, Eanna E. Flanagan, Mark Trodden
We consider theories in which there exists a nontrivial coupling between the dark matter sector and the sector responsible for the acceleration of the universe. Such theories can p…
Preheating in Derivatively-Coupled Inflation Models
Cristian Armendariz-Picon, Mark Trodden, Eric J. West
We study preheating in theories where the inflaton couples derivatively to scalar and gauge fields. Such couplings may dominate in natural models of inflation, in which the flatnes…
