Graceful exit problem in warm inflation

نویسندگان

چکیده

A seemingly simple question, how does warm inflation exit gracefully?, has a more complex answer than in cold paradigm. It been highlighted here that whether exits gracefully depends on three independent choices: The form of the potential, choice model (i.e., its dissipative coefficient) and regime, weak or strong dissipation, characterizing dynamics. Generic conditions slow-roll parameters several constraints different required for to are derived.

Graceful Exit in Extended Inflation and Implications for Density Perturbations

Two qualitatively different modes of ending superluminal expansion are possible in extended inflation. One mode, different from the one envoked in most extended models to date, easily avoids making big bubbles that distort the cosmic microwave background radiation (CMBR). In this mode, the spectrum of density fluctuations is found to be scale-free, P (k) ∝ k, where n might lie anywhere between ...

Inflation Induced by Vacuum Energy and Graceful Exit from it

Motivated by brane cosmology we solve the Einstein equations with a time dependent cosmological constant. Assuming that at an early epoch the vacuum energy scales as 1/logt, we show that the universe passes from a fast growing phase (inflation) to an expanding phase in a natural way.

Graceful exit from a stringy landscape via MSSM inflation

The cosmological evolution of the string landscape is expected to consist of multiple stages of old inflation with large cosmological constant ending by tunneling. Old inflation has a well known graceful exit problem as the observable universe becomes empty, devoid of any entropy. Simultaneously, in the quest for reheating the right degrees of freedom, it is important that the final stage of in...

A modified Starobinsky’s model of inflation: Anomaly-induced inflation, SUSY, and graceful exit

We present a model of inflation based on the anomaly-induced effective action of gravity in the presence of a conformally invariant Hilbert-Einstein term. Our approach is based on the conformal representation of the fields action and on the integration of the corresponding conformal anomaly. In contradistinction to the original Starobinsky’s model, inflation can be stable at the beginning and u...

Axions and the Graceful Exit Problem in String Cosmology

We reexamine the graceful exit problem in the Pre-Big-Bang inflationary scenario. The dilaton-gravity action is generalized by adding the axion and a general axion/dilaton potential. We provide a phase space analysis of the dynamics which leads us to extend the previous no-go theorem and rule out the branch change necessary for graceful exit in this context.
