Inflation-Dark Energy unified through Quantum Regeneration
A. de la Macorra, F. Briscese
We study a scalar phi field that unifies inflation and dark energy with a long period of a hot decelerating universe in between these two stages of inflation. A key feature is that…
Interacting Dark Energy: Decay into Fermions
A. de la Macorra
A dark energy component is responsible for the present stage of acceleration of our universe. If no fine tuning is assumed on the dark energy potential then it will end up dominati…
Massive neutrinos and dark energy
Paolo Serra, Rachel Bean, Axel De La Macorra +1
We consider the impact of the Heidelberg-Moscow claim for a detection of neutrino mass on the determination of the dark energy equation of state. By combining the Heidelberg-Moscow…
The Fate of the Universe: Dark Energy Dilution?
A. de la Macorra
We study the possibility that dark energy decays in the future and the universe stops accelerating. The fact thatthe cosmological observations prefer an equation of state of dark e…
The impact of neutrino masses on the determination of dark energy properties
Axel De La Macorra, Alessandro Melchiorri, Paolo Serra +1
Recently, the Heidelberg-Moscow double beta decay experiment has claimed a detection for a neutrino mass with high significance. Here we consider the impact of this measurement on…
A model of inflation independent of the initial conditions, with bounded number of e-folds and n_s larger orsmaller than one
G. German, A. de la Macorra
We study a supergravity model of inflation essentially depending on one parameter which can be identified with the slope of the potential at the origin. In this type of models the…
