Reconstructing the evolution of dark energy with variations of fundamental parameters

N. J. Nunes, T. Dent, C. J. A. P. Martins +1

Under the assumption that the variations of parameters of nature and the current acceleration of the universe are related and governed by the evolution of a single scalar field, we…

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…

Inflationary Cosmology and Oscillating Universes in Loop Quantum Cosmology

D. J. Mulryne, N. J. Nunes, R. Tavakol +1

We study oscillatory universes within the context of Loop Quantum Cosmology. We make a comparative study of flat and positively curved universes sourced by scalar fields with eithe…

Oscillatory Universes in Loop Quantum Cosmology and Initial Conditions for Inflation

James E. Lidsey, David J. Mulryne, N. J. Nunes +1

Positively-curved, oscillatory universes are studied within the context of Loop Quantum Cosmology subject to a consistent semi-classical treatment. The semi-classical effects are r…
