### Scale-dependent non-Gaussianity probes inflationary physics

- Physics
- 2010

We calculate the scale dependence of the bispectrum and trispectrum in (quasi) local models of non-Gaussian primordial density perturbations, and characterize this scale dependence in terms of new…

### What does inflation really predict?

- Physics
- 2005

If the inflaton potential has multiple minima, as may be expected in, e.g., the string theory ‘landscape’, inflation predicts a probability distribution for the cosmological parameters describing…

### Semiclassical relations and IR effects in de Sitter and slow-roll space-times

- Physics
- 2011

We calculate IR divergent graviton one-loop corrections to scalar correlators in de Sitter space, and show that the leading IR contribution may be reproduced via simple semiclassical consistency…

### Primordial non-Gaussianity from mixed inflaton-curvaton perturbations

- Physics
- 2012

We characterise the primordial perturbations produced due to both inflaton and curvaton fluctuations in models where the curvaton has a quadratic, cosine or hyperbolic potential, and the inflaton…

### Correlated perturbations from inflation and the cosmic microwave background.

- PhysicsPhysical review letters
- 2002

It is found that there is a degeneracy between the amplitude of correlated isocurvature perturbations and the spectral tilt, and estimates of the baryon and CDM densities are found to be almost independent of the isocURvature amplitude.

### Observational test of two-field inflation

- Physics
- 2002

We study adiabatic and isocurvature perturbation spectra produced by a period of cosmological inflation driven by two scalar fields. We show that there exists a model-independent consistency…

### Primordial density perturbation in the curvaton scenario

- Physics
- 2003

We analyze the primordial density perturbation when it is generated by a “curvaton” field different from the inflaton. In some cases this perturbation may have large isocurvature components, fully…

### Observational constraints on the curvaton model of inflation

- Physics
- 2003

Simple curvaton models can generate a mixture of correlated primordial adiabatic and isocurvature perturbations. The baryon and cold dark matter isocurvature modes differ only by an observationally…

### Limit on the detectability of the energy scale of inflation.

- PhysicsPhysical review letters
- 2002

We show that the polarization of the cosmic microwave background can be used to detect gravity waves from inflation if the energy scale of inflation is above 2x10(15) GeV. These gravity waves…

### First-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Implications For Inflation

- Physics
- 2003

We confront predictions of inflationary scenarios with the Wilkinson Microwave Anisotropy Probe (WMAP) data, in combination with complementary small-scale cosmic microwave background (CMB)…

### Adiabatic and entropy perturbations from inflation

- Physics, Environmental Science
- 2000

We study adiabatic ~curvature! and entropy ~isocurvature! perturbations produced during a period of cosmological inflation that is driven by multiple scalar fields with an arbitrary interaction…
