Early Tracking Behavior in Small-field Quintessence Models
We study several quintessence models which are singular at Q = 0, and use a simple initial constraint Qi ≥ Hinflation/2π to see when they enter tracking regime, disregarding the details of inflation. We find it can give strong constraints for the inverse power-law potential V = V0Q −α, which has to enter tracking regime for lnz ∼ 10. While for the supergravity model V = V0Q −αexp(kQ2/2), the co...
متن کاملQuantum Corrections in Quintessence Models
We investigate the impact of quantum fluctuations on a light rolling quintessence field from three different sources, namely, from a coupling to the standard model and dark matter, from its selfcouplings and from its coupling to gravity. We derive bounds for time-varying masses from the change of vacuum energy, finding ∆me/me ≪ 10 for the electron and ∆mp/mp ≪ 10 for the proton since redshift z...
متن کاملTracking Quintessence Would Require Two Cosmic Coincidences
Good tracking requires that the quintessence energy fraction slowly increase while the roll λ ≡ −d lnV/κdφ slowly decreases, but is not yet truly slow-rolling. The supernova bound on the present quintessence equation of state requires either (1) a cosmological constant or other finetuned ”crawling quintessence” or (2) ”roll-over quintessence” that tracked until recently, but now became slow rol...
متن کاملSub-horizon Perturbation Behavior in Extended Quintessence
In the general context of scalar-tensor theories, we consider a model in which a scalar field coupled to the Ricci scalar in the gravitational sector of the Lagrangian, is also playing the role of an “Extended Quintessence” field, dominating the energy content of the Universe at the present time. In this framework, we study the linear evolution of the perturbations in the Quintessence energy de...
متن کاملEarly Quintessence in Light of WMAP
We examine the cosmic microwave background (CMB) anisotropy for signatures of early quintessence dark energy – a non-negligible quintessence energy density during the recombination and structure formation eras. Only very recently does the quintessence overtake the dark matter and push the expansion into overdrive. Because the presence of early quintessence exerts an influence on the clustering ...
