Dark energy, exotic matter and properties of horizons in black hole physics and cosmology
K. A. Bronnikov, E. Elizalde, O. B. Zaslavskii
We summarize recent results on the properties of near-horizon metrics in different spherically symmetric space-times, including Kantowski-Sachs cosmological models whose evolution…
Accelerating cosmologies from non-local higher-derivative gravity
Salvatore Capozziello, Emilio Elizalde, Shin'ichi Nojiri +1
We study accelerating cosmological solutions of a general class of non-linear gravities which depend on Gauss-Bonnet and other higher derivative invariants. To achieve this goal a…
F(R) gravity equation of state
Emilio Elizalde, Pedro J. Silva
The gravity field equations are derived as an equation of state of local space-time thermodynamics. Jacobson's arguments are non-trivially extended, by means of a more…
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…
Black hole collapse simulated by vacuum fluctuations with a moving semi-transparent mirror
Jaume Haro, Emilio Elizalde
Creation of scalar massless particles in two-dimensional Minkowski space-time--as predicted by the dynamical Casimir effect--is studied for the case of a semitransparent mirror ini…
Class of viable modified gravities describing inflation and the onset of accelerated expansion
G. Cognola, E. Elizalde, S. Nojiri +3
A general approach to viable modified gravity is developed in both the Jordan and the Einstein frames. A class of exponential, realistic modified gravities is introduced and…
