Abstract Models of cosmic inflation posit an early phase of accelerated expansion of the universe, driven by the dynamics of one or more scalar fields in curved spacetime. Though detailed assumptions about fields and couplings vary across models, inflation makes specific, quantitative predictions for several observable quantities, such as the flatness parameter ( Ω k = 1 − Ω ) and the spectral tilt of primordial curvature perturbations ( n s − 1 = d ln ⁡ P R / d ln ⁡ k ), among others… Expand
Nonminimal Couplings in the Early Universe: Multifield Models of Inflation and the Latest Observations
Models of cosmic inflation suggest that our universe underwent an early phase of accelerated expansion, driven by the dynamics of one or more scalar fields. Inflationary models make specific,Expand
Inflationary schism after Planck2013
Classic inflation, the theory described in textbooks, is based on the idea that, beginning from typical initial conditions and assuming a simple inflaton potential with a minimum of fine-tuning,Expand
Inflationary Cosmology after Planck 2013
I give a general review of inflationary cosmology and of its present status, in view of the 2013 data release by the Planck satellite. A specific emphasis is given to the new broad class of theories,Expand
Inflation after Planck and BICEP2
We discuss the inflationary paradigm, how it can be tested, and how various models of inflation fare in light of data from Planck and BICEP2. We introduce inflation and reheating, and discussExpand
Cosmological consequences of a principle of finite amplitudes
Over 30 years ago, Barrow & Tipler proposed the principle according to which the action integrated over the entire 4-manifold describing the universe should be finite. Here we explore theExpand
Initial conditions for plateau inflation: a case study
We study initial conditions for inflation in scenarios where the inflaton potential has a plateau shape. Such models are those most favored by Planck data and can be obtained in a large number ofExpand
Constraining the spectrum of cosmological perturbations from statistical thermal fluctuations
Abstract In the standard inflationary paradigm, the seeds for cosmic structures are assumed to be of quantum origin. During inflation, the quantum fluctuations of the fields are stretched by theExpand
Effective field theories as a novel probe of fine-tuning of cosmic inflation
This paper argues that a recent, model-independent characterization of inflation, known as the 'effective field theory (EFT) of inflation', promises to address this question in a thoroughly modern and significantly more comprehensive way than in the existing literature. Expand
New Inflation in the Landscape and Typicality of the Observed Cosmic Perturbation
We investigate if the observed small and nearly scale-invariant primordial cosmic perturbation, i.e. the perturbation amplitude $P_\zeta\sim10^{-9}$ and the spectral index $n_s \simeq 0.965$, isExpand
Conflation: a new type of accelerated expansion
In the framework of scalar-tensor theories of gravity, we construct a new kind of cosmological model that conflates inflation and ekpyrosis. During a phase of conflation, the universe undergoesExpand


Predictions in eternal inflation
In generic models of cosmological inflation, quantum fluctuations strongly influence the spacetime metric and produce infinitely many regions where the end of inflation (reheating) is delayed untilExpand
Inflationary Cosmology after Planck 2013
I give a general review of inflationary cosmology and of its present status, in view of the 2013 data release by the Planck satellite. A specific emphasis is given to the new broad class of theories,Expand
Predictions From Eternal Inflation
We investigate the physics of eternal inflation, particularly the use of multiverse ideas to explain the observed values of the cosmological constant and the coincidences of cosmological timescales.Expand
Coherent phase argument for inflation
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 piecesExpand
Inflationary paradigm in trouble after Planck2013
Recent results from the Planck satellite combined with earlier observations from WMAP, ACT, SPT and other experiments eliminate a wide spectrum of more complex inflationary models and favor modelsExpand
Cosmological implications of the Higgs mass measurement
We assume the validity of the Standard Model up to an arbitrary high-energy scale and discuss what information on the early stages of the Universe can be extracted from a measurement of the HiggsExpand
Inflationary Cosmology: Exploring the Universe from the Smallest to the Largest Scales
Inflation makes several predictions about the present state of the universe—such as its overall shape, large-scale smoothness, and smaller scale structure—which are being tested to unprecedented accuracy by a new generation of astronomical measurements. Expand
Non-Gaussianity from inflation: theory and observations
This is a review of models of inflation and of their predictions for the primordial non-Gaussianity in the density perturbations which are thought to be at the origin of structures in the Universe.Expand
Inflation and eternal inflation
Abstract The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternalExpand
What does inflation really predict
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 describingExpand
