### Implications of Planck2015 for inflationary, ekpyrotic and anamorphic bouncing cosmologies

- Physics
- 2015

The results from Planck2015, when combined with earlier observations from the Wilkinson Microwave Anisotropy Probe, Atacama Cosmology Telescope, South Pole Telescope and other experiments, were the…

### Reconciliation of high energy scale models of inflation with Planck

- Physics
- 2014

The inflationary cosmology paradigm is very successful in explaining the CMB anisotropy to the percent level. Besides the dependence on the inflationary model, the power spectra, spectral tilt and…

### Expectations for inflationary observables: simple or natural?

- Economics
- 2017

We describe the general inflationary dynamics that can arise with a single, canonically coupled field where the inflaton potential is a 4-th order polynomial. This scenario yields a wide range of…

### A viable Starobinsky-like inflationary scenario in the light of Planck and BICEP2 results

- Physics
- 2014

The recent CMB data from Planck and BICEP2 observations have opened a new window for inflationary cosmology. In this paper, we compare three Starobinsky-like inflationary scenarios: (i) The original…

### Hybrid inflation in the complex plane

- Physics
- 2014

Supersymmetric hybrid inflation is an exquisite framework to connect inflationary cosmology to particle physics at the scale of grand unification. Ending in a phase transition associated with…

### BICEP2, Planck, spinorial space-time, pre-Big Bang.

- Physics
- 2015

The field of Cosmology is currently undergoing a positive and constructive crisis. Controversies concerning inflation are not really new. But after the 2013-2014 Planck and BICEP2 announcements, and…

### The best inflationary models after Planck

- Computer Science
- 2014

This analysis singles out the most probable models (from an Occam's razor point of view) that are compatible with Planck data, while ruling out with very strong evidence 34% of the models considered.

### Power-law inflation.

- EconomicsPhysical review. D, Particles and fields
- 1985

A simple inflationary model characterized by a scale factor which grows like Sapprox.t/sup p/, with p a constant greater than one, which is called power-law inflation (PLI), and considers the constraints on this model coming from the requirement of solving the horizon, flatness, ''good'' reheating, and ''convenient'' perturbation-spectrum problems.

### Inflationary universe: A possible solution to the horizon and flatness problems

- Physics
- 1981

The standard model of hot big-bang cosmology requires initial conditions which are problematic in two ways: (1) The early universe is assumed to be highly homogeneous, in spite of the fact that…

### 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 Theory and Alternative Cosmology

- Physics
- 2002

Recently Hollands and Wald argued that inflation does not solve any of the major cosmological problems. We explain why we disagree with their arguments. They also proposed a new speculative mechanism…

### Eternal inflation and its implications

- Economics
- 2007

I summarize the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the…

### On the Degree of Generality of Inflation in Friedmann Cosmological Models with a Massive Scalar Field

- Mathematics
- 1988

Friedmann cosmological models with a massive minimally coupled scalar field are investigated by numerical methods. It is indicated that the majority of the solutions undergo the inflationary stage in…

### Improvement on cosmological chaotic inflation through nonminimal coupling.

- Materials Science, MathematicsPhysical review. D, Particles and fields
- 1990

Non-minimal coupling may provide a relatively simple solution to the long-standing problem of excessive density perturbations in inflationary models.

### Can the universe afford inflation

- Economics
- 2004

Cosmic inflation is envisioned as the 'most likely' start for the observed universe. To give substance to this claim, a framework is needed in which inflation can compete with other scenarios and the…

### Higgs-dilaton cosmology: From the early to the late Universe

- Physics
- 2011

We consider a minimal scale-invariant extension of the standard model of particle physics combined with unimodular gravity formulated in [M. Shaposhnikov and D. Zenhausern, Phys. Lett. B 671, 187…
