Inflation and the cosmological constant
general relativity infl ationary universe cosmological constant
2011/10/14
A particular compensation-type solution of the main cosmological constant problem has been proposed recently, with two massless vector fields dynamically canceling an arbitrary cosmological constant \...
Higgs inflation in minimal supersymmetric SU(5) GUT
Higgs inflation minimal supersymmetric
2011/10/14
The Standard Model Higgs boson with large non-minimal coupling to the gravitational curvature can drive cosmological inflation. We study this type of inflationary scenario in the context of supersymme...
Natural Warm Inflation
Infl ation Axion
2011/10/11
We derive the requirements that a generic axion-like field has to satisfy in order to play the role of the inflaton field in the warm inflation scenario. Compared to the parameter space in ordinary na...
Inflation and primordial non-Gaussianities of "generalized Galileons"
Inflation primordial non-Gaussianities
2011/10/9
We set up cosmological perturbation theory and study the cosmological implications of the so-called `generalized Galileon' developed in \cite{Deffayet:2011gz,horndeski}.This is the most general scalar...
Observational test of inflation in loop quantum cosmology

2011/10/18
We study in detail the power spectra of scalar and tensor perturbations generated during inflation in loop quantum cosmology (LQC). After clarifying in a novel quantitative way how inverse-volume corr...
The No-Boundary Measure in the Regime of Eternal Inflation
no-boundary wave function inflationary histories cosmology infinite universes
2010/3/18
The no-boundary wave function (NBWF) specifies a measure for prediction in cosmology that selects inflationary histories and remains well behaved for spatially large or infinite universes. This paper ...
Minimal Inflation
SUSY cosmology
2010/3/18
Using the universal X superfield that measures in the UV the violation of conformal invariance we build up a model of multifield inflation. The underlying dynamics is the one controlling the natural f...
A brief review of inflation is presented. After having demonstrated the generality of the inflationary mechanism, the emphasis is put on its simplest realization, namely the single field slow-roll inf...
