The higgs portal and an unified model for dark energy and dark matter
(2008-12-10)
We examine a scenario where the Higgs boson is coupled to an additional Standard Model singlet scalar field from a hidden sector. We show that, in the case where this field is very light and has already relaxed to its ...
Dark matter, dark energy, and dark radiation coupled with a transversal interaction
(American Physical Society, 2012-11)
We investigate a cosmological scenario with three interacting components that includes dark matter, dark energy, and radiation in the spatially flat Friedmann-Robertson-Walker universe. We introduce a 3-dimensional internal ...
Dark matter to dark energy transition in k-essence cosmologies
(World Scientific, 2005-12)
We implement the transition from dark matter to dark energy in k-essence cosmologies for a very large set of kinetic functions F, in a way alternative to recent proposals which use generalized Chaplygin gas and transient ...
Observational constraints on holographic tachyonic dark energy in interaction with dark matter
(IOP PUBLISHING LTD, 2010)
We discuss an interacting tachyonic dark energy model in the context of the holographic principle. The potential of the holographic tachyon field in interaction with dark matter is constructed. The model results are compared ...
Non-virialized clusters for detection of dark energy-dark matter interaction
(Oxford Univ Press, 2015-10-11)
The observation of galaxy and gas distributions, as well as cosmological simulations in a Lambda CDM cold dark matter universe, suggests that clusters of galaxies are still accreting mass and are not expected to be in ...

DBI models for the unification of dark matter and dark energy
(Springer/Plenum Publishers, 2010-05)
We propose a model based on a DBI action for the unification of dark matter and dark energy. This is supported by the results of the study of its background behavior at early and late times, and reinforced by the analysis ...
Consequences of dark matter-dark energy interaction on cosmological parameters derived from type Ia supernova data
