Title: Seeding of primordial perturbations during a decelerated expansion

Abstract

A scalar field with a modified dispersion relation may seed, under certain conditions, the primordial perturbations during a decelerated expansion. In this paper we examine whether and how these perturbations can be responsible for the structure formation of the observable universe. We discuss relevant difficulties and possible solutions.

  • Recently, it has been shown that a slow expansion, which is asymptotically a static state in infinite past and may be described as an evolution with {epsilon}<<-1, of early universe may lead to the generation of primordial perturbation responsible for the structure formation of observable universe. However, its feasibility depends on whether the growing mode of Bardeen potential before phase transition can be inherited by the constant mode of curvature perturbation after phase transition. In this paper, we phenomenally regard this slow expansion as that driven by multi-NEC (null energy condition) violating scalar fields. We calculate the curvature perturbation inducedmore » by the entropy perturbation before phase transition and find that the spectrum is naturally scale invariant with a slight red tilt. The result has an interesting similarity to that of slow roll inflation.« less
  • In a previous paper it was claimed that dust, viscously coupled to a background gas undergoing random compressional motion, will cluster secularly. This process was named Purcell clustering. It was suggested that the analogous process in the early universe, the production of isothermal perturbations from adiabatic perturbations, might provide a means for producing a spectrum of isothermal perturbations even if such perturbations were disallowed at t = 0. In this paper the exact rate of clustering is calculated for the case of dust suspended in an ideal gas and for hadrons in the early universe. In addition, computer calculations ofmore » the production of isothermal perturbations in the early universe are presented. These suggest that it may be extremely difficult to produce significant isothermal perturbations of Purcell clustering.« less
  • The perturbation transfer between the rear and front surface (feedout), secular distortion, and Rayleigh-Taylor (R-T) instability growth is studied for long wavelength modes in accelerated flat foils. A simple formula is derived, relating the R-T growth factor to the amplitude of the rear surface perturbation. Comparisons with two-dimensional simulations confirm the validity of the theory. {copyright} {ital 1998} {ital The American Physical Society }
  • Gravitational perturbations are considered in a standard model universe filled with weakly interacting, finite-mass neutrinos and a radiation-dominated plasma. By including the density perturbations in the neutrino gas, one obtains a different law for the evolution of adiabatic perturbations in the plasma. For scalar perturbations, an initial deviation from the background metric will be damped by the kinetic mechanism. The dependence of the damping decrement on the perturbation wave vector is determined.
  • The principle of causality requires that a pure power-law spectrum of cosmological density perturbations possess a super-Hubble suppression scale. We search for evidence of such suppression by performing a three parameter likelihood analysis of the COBE-DMR 4-year sky maps with respect to the amplitude, the spectral index, and the suppression scale. It is found that all suppression scales larger than c/H{sub 0} are consistent with the data, but that scales of order c/H{sub 0} are slightly preferred, at roughly the one-sigma level. Super-Hubble density fluctuations on very large scales ({gt}c/H{sub 0}) can only be explained in the context of presentmore » theory by a de Sitter expansion phase, whereas those that are {open_quotes}small{close_quotes} ({approximately}c/H{sub 0}) can also be explained within the standard hot big-bang model. Density perturbations originating after any conceivable de Sitter expansion phase or during non-isentropic de Sitter expansion have natural kinematic constraints which could explain a small super-Hubble suppression scale. Standard inflationary cosmology, which is characterized by isentropic de Sitter expansion, generically predicts that the particle horizon should be much larger than the present-day Hubble radius, c/H{sub 0}. For such scenarios, a small super-Hubble suppression scale would require the duration of the inflation epoch to be fairly short. Suppression scales smaller than c/H{sub 0} are strongly excluded by the COBE data. {copyright} {ital 1998} {ital The American Physical Society}« less
