Vector field models of modified gravity and the dark sector
J. Zuntz, T. G. Zlosnik, F. Bourliot +2
We present a comprehensive investigation of cosmological constraints on the class of vector field formulations of modified gravity called Generalized Einstein-Aether models. Using…
Geometric flows in Horava-Lifshitz gravity
Ioannis Bakas, Francois Bourliot, Dieter Lust +1
We consider instanton solutions of Euclidean Horava-Lifshitz gravity in four dimensions satisfying the detailed balance condition. They are described by geometric flows in three di…
Mixmaster universe in Horava-Lifshitz gravity
Ioannis Bakas, Francois Bourliot, Dieter Lust +1
We consider spatially homogeneous (but generally non-isotropic) cosmologies in the recently proposed Horava-Lifshitz gravity and compare them to those of general relativity using H…
Cosmological Phases of the String Thermal Effective Potential
Francois Bourliot, John Estes, Costas Kounnas +1
In a superstring framework, the free energy density, F, can be determined unambiguously at the full string level once supersymmetry is spontaneously broken via geometrical fluxes.…
Attraction to a radiation-like era in early superstring cosmologies
Francois Bourliot, Costas Kounnas, Herve Partouche
Starting from an initial classical four dimensional flat background of the heterotic or type II superstrings, we are able to determine at the string one-loop level the quantum corr…
The cosmological behavior of Bekenstein's modified theory of gravity
F. Bourliot, P. G. Ferreira, D. F. Mota +1
We study the background cosmology governed by the Tensor-Vector-Scalar theory of gravity proposed by Bekenstein. We consider a broad family of potentials that lead to modified grav…
