We suggest a scalar model of dark energy with the SO(1, 1) symmetry. The model may be reformulated in terms of a real scalar field Φ and the scale factor a so that the Lagrangian may be decomposed as that of the real quintessence model plus the negative coupling energy term of Φ to a. The existence of the coupling term Lc leads to a wider range of wΦ and overcomes the problem of negative kineti...

We suggest the SO(1, 1) scalar field model of dark energy. In this model, the Lagrangian may be decomposed as that of the real quintessence model and the negative coupling energy term of Φ to a. The existence of the coupling term Lc leads to a wider range of wΦ and overcomes the problem of negative kinetic energy in the phantom universe model. We propose a power-law expansion kinetics model of ...

متن کاملThe dark energy–dominated Universe
In this paper we investigate the epochs in which the Universe started accelerating and when it began to become dark energy–dominated (i.e., the dynamics of the expansion of the Universe dominated by the dark energy). We provide analytic expressions to calculate the redshifts of these epochs as a function of density parameters. Moreover, we review and discuss cosmological models with a dark ener...
متن کاملDark Energy and the Observable Universe
We consider ever-expanding Big Bang models with a cosmological constant, Λ, and investigate in detail the evolution of the observable part of the universe. We also discuss quintessence models from the same point of view. A new concept, the Λ-sphere (or Q-sphere, in the case of quintessence) is introduced. This is the surface in our visible universe which bounds the region where dark energy domi...
