Trapped Quintessential Inflation from Flux Compactifications
نویسنده
چکیده
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 is dominated by contributions due to fluxes in the extra dimensions. The modulus remains frozen until the present, when it can become quintessence.

Trapped Quintessential Inflation in the context of Flux Compactifications
We present a model for quintessential inflation using a string modulus for the inflaton quintessence field. The scalar potential of our model is based on generic non-perturbative potentials arising in flux compactifications. We assume an enhanced symmetry point (ESP), which fixes the initial conditions for slow-roll inflation. When crossing the ESP the modulus becomes temporarily trapped, which...
متن کاملEternal Inflation with α′-Corrections
Higher-order α-corrections are a generic feature of type IIB string compactifications. In KKLT-like models of moduli stabilization they provide a mechanism of breaking the noscale structure of the volume modulus. We present a model of inflation driven by the volume modulus of flux compactifications of the type IIB superstring. Using the effects of gaugino condensation on D7-branes and perturbat...

متن کاملD3-brane Vacua in Stabilized Compactifications
D3-branes feel no force in no-scale flux compactifications of type IIB string theory, but the nonperturbative effects required to stabilize the Kähler moduli break the no-scale structure and generate a potential for D3-brane motion, confining the branes to certain loci. D3-branes away from these loci break supersymmetry spontaneously, by an F-term. We present the general conditions for supersym...
متن کاملA Microscopic Limit on Gravitational Waves from D-brane Inflation
We derive a microscopic bound on the maximal field variation of the inflaton during warped Dbrane inflation. By a result of Lyth, this implies an upper limit on the amount of gravitational waves produced during inflation. We show that a detection at the level r > 0.01 would falsify slow roll D-brane inflation. In DBI inflation, detectable tensors may be possible in special compactifications, pr...
