# Coherent phase argument for inflation

@inproceedings{Dodelson2003CoherentPA, title={Coherent phase argument for inflation}, author={Scott Dodelson}, year={2003} }

Cosmologists have developed a phenomenally successful picture of structure in the universe based on the idea that the universe expanded exponentially in its earliest moments. There are three pieces of evidence for this exponential expansion--inflation--from observations of anisotropies in the cosmic microwave background. First, the shape of the primordial spectrum is very similar to that predicted by generic inflation models. Second, the angular scale at which the first acoustic peak appears is…

The evolution of the inflationary theory is described, starting from the Starobinsky model and the old inflation scenario proposed by Guth, toward chaotic inflation and the modern theory of eternally…

Cosmological perturbations without inflation

- Physics
- 2016

A particularly attractive feature of inflation is that quantum fluctuations in the inflaton field may have seeded inhomogeneities in the cosmic microwave background (CMB) and the formation of…

Since the discovery of the cosmic microwave background (CMB), our understanding of the cosmos has been rapidly evolving. Detailed measurements of the CMB temperature fluctuations have led to a…

Primordial Gravitational Waves and Cosmology

- PhysicsScience
- 2010

The observation of primordial gravitational waves could provide a new and unique window on the earliest moments in the history of the universe and on possible new physics at energies many orders of magnitude beyond those accessible at particle accelerators.

Tests and Problems of the Standard Model in Cosmology

- Physics
- 2017

The main foundations of the standard $$\Lambda $$ΛCDM model of cosmology are that: (1) the redshifts of the galaxies are due to the expansion of the Universe plus peculiar motions; (2) the cosmic…

On the Magnetic Evolution in Friedmann Universes and the Question of Cosmic Magnetogenesis

- PhysicsSymmetry
- 2016

It is claimed that magnetic fields can be superadiabatically amplified after inflation, as long as they remain outside the horizon, which means that inflation-produced fields can reach astrophysically relevant residual strengths without breaking away from standard physics.

Signals of a Quantum Universe.

It is argued here that a detection of primordial non-Gaussianity can resolve the present situation, and provide a litmus test for the quantum origin of cosmic structure.

A Tail of Eternal Inflation

- Physics

Non-trivial inflaton self-interactions can yield calculable signatures of primordial nonGaussianity that are measurable in cosmic surveys. Surprisingly, we find that the phase transition to slow-roll…

Modified dispersion relations, inflation and scale invariance

For a certain type of modified dispersion relations, the vacuum quantum state for very short wavelength cosmological perturbations is scale-invariant and it has been suggested that this may be the…
