Anisotropic multiple bounce models
Anna Paula Bacalhau, Patrick Peter, Sandro D. P. Vitenti
We analyze the Galileon ghost condensate implementation of a bouncing cosmological model in the presence of a non negligible anisotropic stress. We exhibit its structure, which we…
Consistent Scalar and Tensor Perturbation Power Spectra in Single Fluid Matter Bounce with Dark Energy Era
Anna Paula Bacalhau, Nelson Pinto-Neto, Sandro Dias Pinto Vitenti
We investigate cosmological scenarios containing one canonical scalar field with an exponential potential in the context of bouncing models, where the bounce happens due to quantum…
Cosmological dynamics with non-linear interactions
Fabiola Arévalo, Anna Paula Ramos Bacalhau, Winfried Zimdahl
We consider a set of non-linear interactions between dark matter and dark energy which comprises couplings proportional to products of (powers of) the energy densities of both dark…
