False Vacuum Inflation
We review some of the properties of chaotic innation models possessing two scalar elds. One of these (the innaton) rolls while the other is trapped in a false vacuum state which can dominate the energy density. The false vacuum becomes unstable when the magnitude of the innaton eld falls below some critical value, and a rst or second order transition to the true vacuum ensues signalling the end...
متن کاملFalse vacuum inflation with Einstein gravity.
We present a detailed investigation of chaotic inflation models which feature two scalar fields, such that one field (the inflaton) rolls while the other is trapped in a false vacuum state. The false vacuum becomes unstable when the magnitude of the inflaton field falls below some critical value, and a first or second order transition to the true vacuum ensues. Particular attention is paid to t...
متن کاملFalse Vacuum Decay after Inflation
Inflation is terminated by a non-equilibrium process which finally leads to a thermal state. We study the onset of this transition in a class of hybrid inflation models. The exponential growth of tachyonic modes leads to decoherence and spinodal decomposition. We compute the decoherence time, the spinodal time, the size of the formed domains and the homogeneous classical fields within a single ...
متن کاملFalse Vacuum Chaotic Inflation : the New Paradigm ?
Since the observation by COBE of cmb anisotropy at the expected level, the idea that an initial inflationary era sets the conditions for the subsequent hot big bang has enjoyed unprecedented popularity. At the same time, the level of interest in building an actual model of inflation has never been lower. Perhaps the general feeling is that there are already too many theoretically viable models,...
متن کاملCurvature perturbation spectrum from false vacuum inflation
In the inflationary cosmology it occurs frequently that the inflaton field is trapped in a local, transient minimum with non-zero vacuum energy. The difficulty regarding the curvature perturbation produced during such a stage is that classically the inflaton does not move so that the comoving hypersurfaces are not well defined at linear order in the scalar field perturbation. In this paper, ass...
