Inflation and the 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 \...

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...

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...

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...

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...

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 ...

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...

2010/10/26
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...
