A 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
Abstract: I show here that there are some interesting differences between the predictions of warm and cold inflation models focusing in particular upon the scalar spectral index ns and the tensor-to-scalar ratio r. The first thing to be noted is that the warm inflation models in general predict a vanishingly small value of r. Cold inflationary models with the potential V = M4 (φ/MP) p and a num...
متن کاملTowards a theory of Warm Inflation of the Universe
The warm inflation scenario is an alternative mechanism which can explain the isotropic and homogeneous Universe which we are living in. In this work I extend a previously introduced formalism, without the restriction of slow roll regime. Quantum to classical transition of the fluctuations is studied by means of the “transition function” here introduced. I found that the fluctuations of radiati...
متن کاملSpontaneous baryogenesis in warm inflation
We discuss spontaneous baryogenesis in the warm inflation scenario. In contrast with standard inflation models, radiation always exists in the warm inflation scenario, and the inflaton must be directly coupled to it. Also, the transition to the post-inflationary radiation dominated phase is smooth and the entropy is not significantly increased at the end of the period of inflation. In addition,...
متن کاملWarm Inflation Dissipative Dynamics
Warm inflation dynamics is reviewed. Results on dissipative scalar field dynamics relevant to warm inflation are examined and estimates of radiation production are given.
