Interacting Dark Energy
In this paper I discuss some of the phenomenologies of models of the dark energy interacting with the ordinary matter. After a very brief review about the current constraint on the equation of the state of the dark energy from the SN and a new scenario of dark energy the Quintom, I present models of Quintessential Baryo(Lepto)genesis, Quintessino dark matter and mass varying neutrinos in details.
متن کاملInteracting Agegraphic Dark Energy
A new dark energy model, named as “agegraphic dark energy”, has been proposed by one of us (R. G. Cai) in arXiv:0707.4049, based on the Károlyházy uncertainty relation, which arises from the quantum mechanics together with general relativity. In this note, we extend the original agegraphic dark energy model by including the interaction between the agegraphic dark energy and the pressureless (da...
متن کاملInteracting Dark Matter and Dark Energy
We discuss models for the cosmological dark sector in which the energy density of a scalar field approximates Einstein’s cosmological constant and the scalar field value determines the dark matter particle mass by a Yukawa coupling. A model with one dark matter family can be adjusted so the observational constraints on the cosmological parameters are close to but different from what is predicte...
متن کاملGeneralized Interacting Holographic Dark Energy Model
In this manuscript, we present a generalization of the interacting holographic dark energy model using two equations of states for the dark energy: the modified variable Chaplygin gas and the viscous generalized Chaplygin gas. The dynamics of the model are expressed by the use of scalar fields and the scalar potentials. PACS numbers: 98.80.Cq, 98.80.-k, 98.80.Jk ∗[email protected]
متن کاملInteracting Dark Energy in Hořava-Lifshitz Cosmology
Motivated by the recent work of Saridakis [1], we generalize this work to the noninteracting case. Using an additional canonical scalar field, we formulate HořavaLifshitz cosmology with an effective interacting dark energy sector. ∗E-mail: [email protected]
