Two-stage Innation in Supergravity
نویسندگان
چکیده
We investigate the viability of a two-stage innationary scenario in the context of super-gravity, so as to resolve the problem of initial conditions for hybrid innation. We allow for non-renormalizable terms in the superpotential and consider the most general form of the KK ahler potential and the gauge kinetic function. We construct a model with two stages of innation, the rst driven by D-term and the second by F-term energy density. The viability of this scenario depends on the non-minimal terms in the KK ahler potential, for which we derive the necessary constraints.

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 کاملInnation, Volatility and Growth
This paper reexamines the relationship between innation, innation volatility and growth using crosscountry panel data for the past 30 years. With regard to the level of innation, we nd that in contrast to current ndings which are based on cross-sectional time-average regression comparisons, exploiting the time dimension of the data reveals a strong negative correlation between innation and inco...
متن کاملOn Innation as a Regressive Consumption Tax
Evidence on the portfolio holdings and transaction patterns of households suggests that the burden of innation is not evenly distributed. We build a monetary growth model consistent with key features of cross-sectional household data and use this framework to study the distributional impact of innation. At the aggregate level, our model economy behaves similarly to standard monetary growth mode...
متن کاملCan Innation Be Falsiied?
Despite its central role in modern cosmology, doubts are often expressed as to whether cos-mological innation is really a falsiiable theory. We distinguish two facets of innation, one as a theory of initial conditions for the hot big bang and the other as a model for the origin of structure in the Universe. We argue that the latter can readily be excluded by observations, and that there are als...
متن کاملSussex-ast-94/7-1 Astro-ph/yymmnnn First Order Innation in General Relativity 1
I give a general formulation of the constraints on models of innation ended by a rst order phase transition arising from the requirement that they do not produce too many large (observable) true vacuum voids { thèbig bubble problem'. It is shown that this constraint can be satissed by a simple model in Einstein gravity { a variant of`hybrid' or`false vacuum' innation. The idea that innation cou...
