Stationary vs. singular points in an accelerating FRW cosmology derived from six-dimensional Einstein-Gauss-Bonnet gravity
E. Elizalde, A. N. Makarenko, V. V. Obukhov +2
Six-dimensional Einstein-Gauss-Bonnet gravity (with a linear Gauss-Bonnet term) is investigated. This theory is inspired by basic features of results coming from string and M-theor…
String-inspired Gauss-Bonnet gravity reconstructed from the universe expansion history and yielding the transition from matter dominance to dark energy
Guido Cognola, Emilio Elizalde, Shin'ichi Nojiri +2
We consider scalar-Gauss-Bonnet and modified Gauss-Bonnet gravities and reconstruct these theories from the universe expansion history. In particular, we are able to construct vers…
Uses of zeta regularization in QFT with boundary conditions: a cosmo-topological Casimir effect
Emilio Elizalde
Zeta regularization has proven to be a powerful and reliable tool for the regularization of the vacuum energy density in ideal situations. With the Hadamard complement, it has been…
Hamiltonian approach to the dynamical Casimir effect
Jaume Haro, Emilio Elizalde
A Hamiltonian approach is introduced in order to address some severe problems associated with the physical description of the dynamical Casimir effect at all times. For simplicity,…
Dark energy in modified Gauss-Bonnet gravity: late-time acceleration and the hierarchy problem
Guido Cognola, Emilio Elizalde, Shin'ichi Nojiri +2
Dark energy cosmology is considered in a modified Gauss-Bonnet (GB) model of gravity where an arbitrary function of the GB invariant, , is added to the General Relativity act…
Modified Gravity on the Brane and Dark Energy
Emilio Elizalde, Rui Neves
We analyze the dynamics of an AdS5 braneworld with matter fields when gravity is allowed to deviate from the Einstein form on the brane. We consider exact 5-dimensional warped solu…
