Non-linear non-local Cosmology
N. J. Nunes, D. J. Mulryne
Non-local equations of motion contain an infinite number of derivatives and commonly appear in a number of string theory models. We review how these equations can be rewritten in t…
Constraints on a scale invariant power spectrum from superinflation in LQC
D. J. Mulryne, N. J. Nunes
The computation of the spectrum of primordial perturbations, generated by a scalar field during the super-inflationary phase of Loop Quantum Cosmology, is revisited. The calculatio…
Inflation: A graceful entrance from Loop Quantum Cosmology
N. J. Nunes
The evolution of a scalar field is explored taking into account the presence of a background fluid in a positively curved Universe in the framework of loop quantum cosmology. Thoug…
Number counts in homogeneous and inhomogeneous dark energy models
N. J. Nunes, A. C. da Silva, N. Aghanim
In the simple case of a constant equation of state, redshift distribution of collapsed structures may constrain dark energy models. Different dark energy models having the same ene…
Applications of scalar attractor solutions to Cosmology
S. C. C. Ng, N. J. Nunes, F. Rosati
We develop a framework to study the phase space of a system consisting of a scalar field rolling down an arbitrary potential with varying slope and a background fluid, in a cosmolo…
