Eternal Inflation when in the presence of dissipation and quantum and thermal noise effects |
|
Abstract |
Nonisentropic inflation models attempt to fully account for the quantum effects that other field degrees of freedom, other than the inflaton field, might cause on the inflaton dynamics. In particular, it is known that these quantum effects can produce both quantum and thermal stochastic noise and dissipation terms in the inflaton's equation of motion. Here we analyze how these quantum and thermal effects can alter the possibility for producing eternal inflation in the context of different potentials for the inflaton. It is shown how these quantum generated terms can reduce the probability of the universe entering in a regime of eternal inflation and the resulting implications are discussed. |
