Abstract

We study the dynamics of a classical scalar field that rolls down a linear potential as it interacts bi-quadratically with a quantum field. We explicitly solve the dynamical problem by using the classical-quantum correspondence (CQC). Rolling solutions on the effective potential are shown to compare very poorly with the full solution. Spatially homogeneous initial conditions maintain their homogeneity and small inhomogeneities in the initial conditions do not grow.

Inflation in an exponential-potential scalar field model

Journal Article Ratra, B. - Physical Review, D (Particles Fields); (United States)

A spatially flat cosmological scalar field ({Phi}) model with the scalar field potential {proportional to}exp({minus}{Phi}/ {radical}{ital p} ), {ital p}{gt}1 provides a simple class of inflationary cosmologies (which includes the usual exponential expansion inflation) that may be used as an analytical testing ground to help understand the predictions of the inflation model of the very early Universe. We divide the evolution of this model into three distinct epochs: scalar-field dominance and conventional radiation and baryon dominance; in each epoch we only account for irregularities in the dominant form of matter. We present closed-form solutions of the (synchronous gauge) relativistic linearmore »« less

Inflation in a closed universe

Journal Article Ratra, Bharat - Physical Review D

To derive a power spectrum for energy density inhomogeneities in a closed universe, we investigate a spatially-closed inflation-modified hot big bang model whose evolutionary history is divided into three epochs: an early slowly-rolling scalar field inflation epoch and the usual radiation and nonrelativistic matter epochs. (For our usage it is not necessary to consider a final dark energy dominated epoch.) We derive general solutions of the relativistic linear perturbation equations in each epoch. The constants of integration in the inflation epoch solutions are determined from de Sitter invariant quantum-mechanical initial conditions in the Lorentzian section of the inflating closed demore »« less

Evolution equation for the expectation value of a scalar field in spatially flat RW universes

Journal Article Ringwald, A. - Ann. Phys. (N.Y.); (United States)

The backreaction of quantum fluctuations on the evolution of a c-number background field shows up in the appearance of new terms beside the classical ones in the effective evolution equation. We calculate the one loop correction to the field equation of the expectation value phi/sub c/equivalent>phi.< of the field operator phi in a lambdaphi/sup 4/ theory in spatially flat Robertson--Walker universes in an adiabatic approximation scheme. This approximation scheme is valid if the evolution time scale of the background metric and the background scalar field phi/sub c/ is much slower than the quantum fluctuation time scale.

Beginning inflation in an inhomogeneous universe

Journal Article East, William E. ; Kleban, Matthew ; Linde, Andrei ; ... - Journal of Cosmology and Astroparticle Physics

Using numerical solutions of the full Einstein field equations coupled to a scalar inflaton field in 3+1 dimensions, we study the conditions under which a universe that is initially expanding, highly inhomogeneous and dominated by gradient energy can transition to an inflationary period. If the initial scalar field variations are contained within a sufficiently flat region of the inflaton potential, and the universe is spatially flat or open on average, inflation will occur following the dilution of the gradient and kinetic energy due to expansion. This is the case even when the scale of the inhomogeneities is comparable to themore »« less
