Stochastic Inflationary Scalar Electrodynamics
We stochastically formulate the theory of scalar quantum electrodynamics on a de Sitter background. This reproduces the leading infrared logarithms at each loop order. It also allows one to sum the series of leading infrared logarithms to obtain explicit, nonperturbative results about the late time behavior of the system. One consequence is confirmation of the conjecture by Davis, Dimopoulos, P...
متن کاملStochastic gravitational waves backgrounds: a probe for inflationary and non-inflationary cosmology
Physical scenarios, leading to highly energetic stochastic gravitational waves backgrounds (for frequencies ranging from the μHz up to the GHz) are examined. In some cases the typical amplitude of the logarithmic energy spectrum can be even eight orders of magnitude larger than the ordinary inflationary prediction. Scaling violations in the frequency dependence of the energy density of the prod...
متن کاملStationary solutions in Brans-Dicke stochastic inflationary cosmology.
In Brans–Dicke theory the Universe becomes divided after inflation into many exponentially large domains with different values of the effective gravitational constant. Such a process can be described by diffusion equations for the probability of finding a certain value of the inflaton and dilaton fields in a physical volume of the Universe. For a typical chaotic inflation potential, the solutio...

متن کاملINFLATIONARY EQUILIBRIUM IN A STOCHASTIC ECONOMY WITH INDEPENDENT AGENTS By
We prove the existence of stationary monetary equilibrium with inflation in a ‘‘Bewley’’ model with constant aggregate real variables but with idiosyncratic shocks to the endowments of a continuum of individual agents, when a central bank stands ready to borrow or lend fiat money at a fixed nominal rate of interest and the agents face borrowing constraints. We also find that, in the presence of...
