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…
Twisted Hopf symmetries of canonical noncommutative spacetimes and the no-pure-boost principle
Giovanni Amelino-Camelia, Fabio Briscese, Giulia Gubitosi +3
We study the twisted-Hopf-algebra symmetries of observer-independent canonical spacetime noncommutativity, for which the commutators of the spacetime coordinates take the form [x^{…
Black hole entropy in modified gravity models
F. Briscese, E. Elizalde
An analysis of some modified gravity models, based on the study of pure Schwarzschild and of Schwarzschild-de Sitter black holes, and involving the use of the Noether charge method…
Cosmological Casimir effect with maximum planckian momentum and accelerating universe
F. Briscese, A. Marciano
We develop here a mechanism that, without making use of a cosmological constant, reproduces an accelerating universe. This is done by taking into account Casimir vacuum energy dens…
Phantom scalar dark energy as modified gravity: understanding the origin of the Big Rip singularity
F. Briscese, E. Elizalde, S. Nojiri +1
It is shown that phantom scalar models can be mapped into a mathematically equivalent, modified gravity, which turns out to be complex, in general. Only for even scalar pote…
