Singularities in loop quantum cosmology
Thomas Cailleteau, Antonio Cardoso, Kevin Vandersloot +1
We show that simple scalar field models can give rise to curvature singularities in the effective Friedmann dynamics of Loop Quantum Cosmology (LQC). We find singular solutions for…

Scalar perturbations in DGP braneworld cosmology
Antonio Cardoso
We solve for the behaviour of cosmological perturbations in the Dvali-Gabadadze-Porrati (DGP) braneworld model using a new numerical method. Unlike some other approaches in the lit…

Generalised perturbation equations in bouncing cosmologies
Antonio Cardoso, David Wands
We consider linear perturbation equations for long-wavelength scalar metric perturbations in generalised gravity, applicable to non-singular cosmological models including a bounce…
