### Nonminimal Couplings in the Early Universe: Multifield Models of Inflation and the Latest Observations

- Physics
- 2015

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,…

### CMB constraints on β-exponential inflationary models

- Economics
- 2018

We analyze a class of generalized inflationary models proposed in ref. [1], known as β-exponential inflation. We show that this kind of potential can arise in the context of brane cosmology, where…

### Inflationary Cosmology after Planck 2013

- Physics
- 2014

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,…

### Cosmological consequences of a principle of finite amplitudes

- Physics
- 2021

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 the…

### New inflation in the landscape and typicality of the observed cosmic perturbation

- PhysicsPhysical Review D
- 2019

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 $n_s \simeq 0.965$, is…

### Initial conditions for plateau inflation: a case study

- EconomicsJournal of Cosmology and Astroparticle Physics
- 2020

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 of…

### Conflation: a new type of accelerated expansion

- Physics
- 2015

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 undergoes…

### Assessing the scientific status of inflation after Planck

- EconomicsPhysical Review D
- 2019

Inflation is considered as the best theory of the early universe by a very large fraction of cosmologists. However, the validity of a scientific model is not decided by counting the number of its…

### Predictions in eternal inflation

- Physics
- 2008

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 until…

### Coherent phase argument for inflation

- Physics
- 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…

### Cosmological implications of the Higgs mass measurement

- Physics
- 2007

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 Higgs…

### Inflationary Cosmology: Exploring the Universe from the Smallest to the Largest Scales

- PhysicsScience
- 2005

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.

### 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…

### The inflationary Universe

- Physics
- 1984

According to the inflationary Universe scenario the Universe in the very early stages of its evolution was exponentially expanding in the unstable vacuumlike state. At the end of the exponential…
