# Inflationary paradigm in trouble after Planck2013

@article{Ijjas2013InflationaryPI, title={Inflationary paradigm in trouble after Planck2013}, author={Anna Ijjas and Paul J. Steinhardt and Abraham Loeb}, journal={Physics Letters B}, year={2013}, volume={723}, pages={261-266} }

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 models with a single scalar field, as reported by the Planck Collaboration. More important, though, is that all the simplest inflaton models are disfavored statistically relative to those with plateau-like potentials. We discuss how a restriction to pl ateau-like models has three independent serious… Expand

Implications of Planck2015 for inflationary, ekpyrotic and anamorphic bouncing cosmologies

- Physics
- 2015

The results from Planck2015, when combined with earlier observations from WMAP, ACT, SPT and other experiments, were the first observations to disfavor the "classic" inflationary paradigm. To satisfy… Expand

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… Expand

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… Expand

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

Power-law inflation.

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.
