Superinflation and quintessence in the presence of an extra field
نویسندگان
چکیده
We discuss the implication of the introduction of an extra field to the dynamics of a scalar field conformally coupled to gravitation in a homogeneous isotropic spatially flat universe. We show that for some reasonable parameter values the dynamical effects are similar to those of our previous model with a single scalar field. Nevertheless for other parameter values new dynamical effects are obtained. PACS: 98.80.Cq, 98.80.Bp, 98.80.Hw

Natural Theories of Ultra–Low Mass PNGB’s: Axions and Quintessence
We consider the Wilson Line PNGB which arises in a U(1) gauge theory, abstracted from a latticized, periodically compactified extra dimension U(1). Planck scale breaking of the PNGB’s global symmetry is suppressed, providing natural candidates for the axion and quintessence. We construct an explicit model in which the axion may be viewed as the 5th component of the U(1)Y gauge field in a 1+4 la...
متن کاملTrapped Quintessential Inflation from Flux Compactifications
Quintessential inflation is studied using a string modulus as the inflaton– quintessence field. It is assumed that the modulus crosses an enhanced symmetry point (ESP) in field space. Particle production at the ESP temporarily traps the modulus resulting in a period of inflation. After reheating, the modulus freezes due to cosmological friction at a large value, such that its scalar potential i...
متن کاملCoupling Quintessence to Inflation in Supergravity
The evolution of the quintessence field during a phase of chaotic inflation is studied. The inflaton φ and the quintesssence field Q are described in a supergravity framework where the coupling between the inflaton and quintessence is induced by non-renormalisable operators suppressed by the Planck mass. We show that the resulting quintessence potential during inflation possesses a time–depende...
متن کاملThe SUGRA Quintessence Model Coupled to the MSSM
We study the cosmological evolution of the universe when quintessence is modeled within supergravity, supersymmetry is broken in a hidden sector, and we also include observable matter in a third independent sector. We find that the presence of hidden sector supersymmetry breaking leads to modifications of the quintessence potential. We focus on the coupling of the SUGRA quintessence model to th...
متن کاملOn the relativity of shapes
As has been widely discussed [1], the presence of extra dimensions may provide a possible explanation not only for the hierarchy problem of the fundamental interactions, but also for the late time cosmic acceleration, with no need to invoke either a cosmological constant Λ or a quintessence field Φ. In this paper we use a model independent formulation of the so-called brane-world program [2, 3]...
