Relaxing a large cosmological constant
Florian Bauer, Joan Sola, Hrvoje Stefancic
The cosmological constant (CC) problem is the biggest enigma of theoretical physics ever. In recent times, it has been rephrased as the dark energy problem in order to encompass a…
Future of the universe in modified gravitational theories: Approaching to the finite-time future singularity
Kazuharu Bamba, Shin'ichi Nojiri, Sergei D. Odintsov
We investigate the future evolution of the dark energy universe in modified gravities including gravity, string-inspired scalar-Gauss-Bonnet and modified Gauss-Bonnet ones,…
Reconstructing the universe history, from inflation to acceleration, with phantom and canonical scalar fields
Emilio Elizalde, Shin'ichi Nojiri, Sergei D. Odintsov +2
We consider the reconstruction technique in theories with a single or multiple (phantom and/or canonical) scalar fields. With the help of several examples, it is demonstrated expli…
Dark energy generated from a (super)string effective action with higher order curvature corrections and a dynamical dilaton
E. Elizalde, S. Jhingan, S. Nojiri +3
We investigate the possibility of a dark energy universe emerging from an action with higher-order string loop corrections to Einstein gravity in the presence of a massless dilaton…
