De Sitter cosmology from Gauss-Bonnet dark energy with quantum effects
Emilio Elizalde, John Quiroga Hurtado, Hector Ivan Arcos
A Gauss-Bonnet dark energy model is considered, which is inspired in string/M-theory and takes also into account quantum contributions. Those are introduced from a conformal quantu…
Vanishing Cosmological Constant in Modified Gauss-Bonnet Gravity with Conformal Anomaly
Iver Brevik, John Quiroga Hurtado
We consider dark energy cosmology in a de Sitter universe filled with quantum conformal matter. Our model represents a Gauss-Bonnet model of gravity with contributions from quantum…
Tachyon fields with effects of quantum matter in an Anti-de Sitter Universe
Emilio Elizalde, John Quiroga Hurtado
We consider an Anti-de Sitter universe filled by quantum conformal matter with the contribution from the usual tachyon and a perfect fluid. The model represents the combination of…
Inflationary Dilatonic de Sitter Universe from cal N = 4 Super Yang - Mills Theory Perturbed by Scalars
John Quiroga Hurtado
In this paper a quantum N = 4 super Yang-Mills theory perturbed by dilaton-coupled scalars, is considered. The induced effective action for such a theory is calculated on a dilaton…
Role of the Dilatonic potential to the Quantum stabilization of dilatonic Anti-de Sitter Universe
J. Quiroga Hurtado, H. I. Arcos, W. Ardila
Quantum effects lead to the annihilation of AdS Universe when dilaton is absent. We consider here the role of the form for the dilatonic potential in the quantum creation of a dila…
Quantum stabilization of dilatonic Anti-de Sitter Universe
John Quiroga Hurtado, Yulia A. Shaido
The possibility of quantum creation of a dilatonic AdS Universe is discussed.Without dilaton it is known that quantum effects lead to the annihilation of AdS Universe. We consider…
