Inflationary Universe Phenomenology  

In General > s.a. [inflation]; astronomical objects [B field]; chaos in gravitation; cosmological acceleration; Curvaton.
* Predictions: Scale-invariant power spectrum at low ; Peak in the power spectrum of cmb inhomogeneities at 1o (corresponding to the largest inhomogeneities at recombination time); Further "rebound" peaks depend on details of the early universe (like the harmonic content of a musical instrument!).
* 2000: Confirmation of 1o peak in cmb power spectrum from Boomerang (which also saw R = 0) and Maxima.
* 2001: DASI at NSF's South Pole station saw second and third peaks; More data (including on cmb polarization) are expected soon from these experiments and CBI & MAP; Later, look at agreement with observation of gravitational waves from earlier times.
* 2004: Inflationary cosmology has provided a predictive and phenomenologically very successful scenario for early-universe cosmology, [but] attempts to implement inflation using scalar fields lead to models with serious conceptual problems [R Brandenberger].
* 2006: Agreement improves with cmb polarization results, which show departure from flat Harrison-Zel'dovich spectrum.
* 2007: The basic predictions of inflation (regarding the cmb) are all supported by the data; The predicted deviation from a scale-invariant spectrum and the production of primordial gravitational waves have not been well tested yet, but can be by future experiments.

Fluctuations or Perturbations > s.a. cosmological perturbations; gravitational radiation; quantum field theory in curved backgrounds.
* Idea: Quantum theory produces small fluctuations in the energy density ( 10–60); Those fluctuations expand outside H–1, become classical when virtual quanta are pulled apart by expansion, keep growing because of gravity (one needs a changing equation of state), and reenter the horizon now being of order 1.
