Effective cosmological “constant” and quintessence
نویسندگان
چکیده
In this paper we present exactly solved extended quintessence models; furthermore, through a dynamical effective Q-cosmological ”constant”, we recover some of the Λ decaying cases found in the literature. Finally we introduce a sort of complementarity between the Q-dominated or Λdominated expansions of the Universe. e-mail addresses: [email protected] [email protected]

An alternative to a cosmological constant is quintessence, defined as a slowlyvarying scalar field potential V (φ). If quintessence is observationally significant, an epoch of inflation is beginning at the present epoch, with φ the slowly-rolling inflaton field. In contrast with ordinary inflation, quintessence seems to require extreme fine tuning of the potential V (φ). The degree of fine-tuni...
متن کاملM ar 2 00 2 On the Cosmological Constant Problems and the Astronomical Evidence for a Homogeneous Energy Density with Negative Pressure ∗
In this article the cosmological constant problems, as well as the astronomical evidence for a cosmologically significant homogeneous exotic energy density with negative pressure (quintessence), are reviewed for a broad audience of physicists and mathematicians. After a short history of the cosmological term it is explained why the (effective) cosmological constant is expected to obtain contrib...
متن کاملNonlinear evolution of spherical perturbation in the Universe with cosmological constant and quintessence
We generalize the spherical collapse model for the formation of bound objects to apply in a Universe with cosmological constant and quintessence. We calculate the critical condition for collapse of an overdense region and give exact values of the characteristic densities and redshifts of its evolution. We apply the results to calculate the mass function of bound objects. Comparison with the dat...
متن کاملCosmological Constant and Axions in String Theory
String theory axions appear to be promising candidates for explaining cosmological constant via quintessence. In this paper, we study conditions on the string compactifications under which axion quintessence can happen. For sufficiently large number of axions, cosmological constant can be accounted for as the potential energy of axions that have not yet relaxed to their minima. In compactificat...
متن کاملQuintessence Cosmology and the Cosmic Coincidence
Within present constraints on the observed smooth energy and its equation of state parameter wQ = P/ρQ, it is important to find out whether the smooth energy is static (cosmological constant) or dynamic (quintessence). The most dynamical quintessence fields observationally allowed are now still fast-rolling and no longer satisfy the tracker approximation if the equation of state parameter varie...
