Thermal Inflation and the Gravitational Wave Background
Richard Easther, John T. Giblin, Eugene A. Lim +2
We consider the impact of thermal inflation -- a short, secondary period of inflation that can arise in supersymmetric scenarios -- on the stochastic gravitational wave background.…
Wronskian Formulation of the Spectrum of Curvature Perturbations
Shuichiro Yokoyama, Takahiro Tanaka, Misao Sasaki +1
We present a new formulation for the evaluation of the primordial spectrum of curvature perturbations generated during inflation, using the fact that the Wronskian of the scalar fi…
From the Spectrum to Inflation: A Second Order Inverse Formula for the General Slow-Roll Spectrum
Minu Joy, Ewan D. Stewart
We invert the second order, single field, general slow-roll formula for the power spectrum, to obtain a second order formula for inflationary parameters in terms of the primordial…
A New delta N Formalism for Multi-Component Inflation
Hyun-Chul Lee, Misao Sasaki, Ewan D. Stewart +2
The delta N formula that relates the final curvature perturbation on comoving slices to the inflaton perturbation on flat slices after horizon crossing is a powerful and intuitive…
Precision of Inflaton Potential Reconstruction from CMB Using the General Slow-Roll Approximation
Kenji Kadota, Scott Dodelson, Wayne Hu +1
Through a principal component analysis, we study how accurately CMB observables can constrain inflaton potentials in a model independent manner. We apply the general slow-roll appr…
From the Spectrum to Inflation : An Inverse Formula for the General Slow-Roll Spectrum
Minu Joy, Ewan D. Stewart, Jinn-Ouk Gong +1
We propose a general inverse formula for extracting inflationary parameters from the observed power spectrum of cosmological perturbations. Under the general slow-roll scheme, whic…
