Brans-Dicke brane cosmology
Luis E. Mendes, Anupam Mazumdar
A five dimensional brane cosmology with non-minimally coupled scalar field to gravity has been considered in a Jordan-Brans-Dicke frame. We derive an effective four dimensional fie…
Early cosmology and the stochastic gravitational wave background
Luis E Mendes, Andrew R Liddle
The epoch when the Universe had a temperature higher than a GeV is long before any time at which we have reliable observations constraining the cosmological evolution. For example,…
Inflating Defects
Patricio S. Letelier, Luis E. Mendes
A Kantowski-Sachs cosmological model with an O(3) global defect as a source is studied in the context of the topological inflation scenario.
An Exact Calculation of the Energy Density of Cosmological Gravitational Waves
L. E. Mendes, A. B. Henriques, R. G. Moorhouse
In this paper we calculate the Bogoliubov coefficients and the energy density of the stochastic gravitational wave background for a universe that undergoes inflation followed by ra…
