Inflationary universe in loop quantum cosmology [PDF]
, 2007 Loop quantum cosmology provides a nice solution of avoiding the big bang singularity through a big bounce mechanism in the high energy region. In loop quantum cosmology an inflationary universe is emergent after the big bounce, no matter what matter ...

Effect of inflation on anisotropic cosmologies [PDF]
Physical Review D, 1986 The effects of anisotropic cosmologies on inflation are studied. By properly formulating the field equations it is possible to show that any model that undergoes sufficient inflation will become isotropic on scales greater than the horizon today.

Pre-Big-Bang in String Cosmology [PDF]
, 1998 We compute the amount of inflation required to solve the horizon problem of cosmology in the pre-big-bang scenario. First we give a quick overview of string cosmology as developed by Veneziano and collaborators.

Inflation and the cosmological constant [PDF]
Physical Review D, 2012 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 naive expectation is that such a compensation mechanism does not allow for the existence of an inflationary phase in the very early Universe ...

Holographic cosmology and tachyon inflation [PDF]
International Journal of Modern Physics A, 2018 After a brief introduction to the AdS/CFT holography, a tachyon inflation will be discussed in the framework of holographic cosmology. The model is based on a holographic braneworld scenario with an effective tachyon field on a D3-brane located at the holographic bound of an asymptotic ADS5 bulk.

Reheating via gravitational particle production in simple models of quintessence or $\Lambda$CDM inflation [PDF]
, 2017 We have tested some simple $\Lambda$CDM (the same test is also valid for quintessence) inflation models, imposing that they match with the recent observational data provided by the BICEP and Planck's team and leading to a reheating temperature, which is ...

Inflation from Supersymmetric Quantum Cosmology [PDF]
, 1996 We derive a special scalar field potential using the anisotropic Bianchi type I cosmological model from canonical quantum cosmology under determined conditions in the evolution to anisotropic variables $\beta_\pm$.
