THE HIGGS PORTAL and AN UNIFIED MODEL FOR DARK ENERGY and DARK MATTER
(World Scientific Publ Co Pte Ltd, 2013)
Consequences of dark matter-dark energy interaction on cosmological parameters derived from type Ia supernova data
(American Physical Soc, 2007-04-01)
Models where the dark matter component of the Universe interacts with the dark energy field have been proposed as a solution to the cosmic coincidence problem, since in the attractor regime both dark energy and dark matter ...

Models where the dark matter component of the Universe interacts with the dark energy field have been proposed as a solution to the cosmic coincidence problem, since in the attractor regime both dark energy and dark matter ...
Energia escura acoplada
(Universidade Estadual Paulista (Unesp), 2010-02-26)
Na última década várias observações indicam que o universo está expandindo aceleradamente. Essa expansão acelerada pode ser explicada em um universo composto de 70% de energia escura e 30% de matéria (25% de matéria escura ...
Interacting dark sector with variable vacuum energy
(Amer Physical Soc, 2013-10)
We examine a cosmological scenario where dark matter is coupled to a variable vacuum energy while baryons and photons are two decoupled components for a spatially flat Friedmann-Robertson-Walker spacetime. We apply the χ2 ...
Ghost Dark Energy Model with Non-linear Interaction
(2018-07-23)
In this paper we study a dark energy model taking into account a non-linear
interaction between the dark energy and dark matter components. The non-linear
interaction term, used in this work, is proportional to the square ...
Interacting dark matter and cosmic acceleration
(EDP SciencesSocietà Italiana di FisicaSpringer Berlin Heidelberg, 2020)
We study the effect of an explicit interaction between two scalar fields components describing dark matter in the context of a recent proposal framework for interaction. We find that, even assuming a very small coupling, ...
δ Gravity: Dark Sector, Post-Newtonian Limit and Schwarzschild Solution
(2019)
We present a new kind of model, which we call Theories, where standard theories are modified including new fields, motivated by an additional symmetry ( symmetry). In previous works, we proved that Theories just ...
Can dark matter decay in dark energy?
(AMER PHYSICAL SOC, 2009)
We analyze the interaction between dark energy and dark matter from a thermodynamical perspective. By assuming they have different temperatures, we study the possibility of occurring a decay from dark matter into dark ...
