The "in-in" Formalism and Cosmological Perturbations
Peter Adshead, Richard Easther, Eugene A. Lim
We describe an efficient scheme for evaluating higher order contributions to primordial cosmological perturbations using the "in-in" formalism, which is the basis of modern calcula…
CMBPol Mission Concept Study: Probing Inflation with CMB Polarization
Daniel Baumann, Mark G. Jackson, Peter Adshead +56
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…
Neutrinos and Future Concordance Cosmologies
Peter Adshead, Richard Easther
We review the free parameters in the concordance cosmology, and those which might be added to this set as the quality of astrophysical data improves. Most concordance parameters en…
Cosmology With Many Light Scalar Fields: Stochastic Inflation and Loop Corrections
Peter Adshead, Richard Easther, Eugene A. Lim
We explore the consequences of the existence of a very large number of light scalar degrees of freedom in the early universe. We distinguish between participator and spectator fiel…
Constraining Inflation
Peter Adshead, Richard Easther
Slow roll reconstruction is derived from the Hamilton-Jacobi formulation of inflationary dynamics. It automatically includes information from sub-leading terms in slow roll, and fa…
