Fresh inflation: a warm inflationary model from a zero temperature initial state
A two components mixture fluid which complies with the gamma law is considered in the framework of inflation with finite temperature. The model is developed for a quartic scalar potential without symmetry breaking. The radiation energy density is assumed to be zero when inflation starts and remains below the GUT temperature during the inflationary stage. Furthermore, provides the necessary numb...
متن کاملFresh inflation from five-dimensional vacuum state
I study fresh inflation from a five-dimensional vacuum state, where the fifth dimension is constant. In this framework, the universe can be seen as inflating in a four-dimensional Friedmann-Robertson-Walker metric embedding in a five-dimensional metric. Finally, the experimental data ns = 1 (BOOMERANG-98 and MAXIMA-1, taken together COBE DMR), are consistent with p+ρt ρt ≃ 1/3 in the fresh infl...
متن کاملA Quantum Field Theory Warm Inflation Model
A quantum field theory warm inflation model is presented that solves the cosmological horizon/flatness problems. An interpretation of the model is given from supersymmetry and superstring theory. To appear in Proceedings COSMOS 98, Monterey, CA, November 1998
متن کاملWarm Inflation at Arbitrary Adiabaticity - a Model, an Existence Proof for Inflationary Dynamics in Quantum Field Theory
Warm inflation is examined in a multi-field model. Solutions are obtained for expansion e-folds and scalar density perturbations. Nonequilibrium dynamics is restricted to a regime that is displaced only slightly from thermal equilibrium and in which all macroscopic motion is adiabatic. In such a regime, nonequilibrium dynamics is well defined, provided macroscopic motions that displace the ther...
