Inflation in inhomogeneous cosmology

Physical Review D, 1992
We discuss the onset of inflation in an inhomogeneous, asymptotically Friedmann-Robertson-Walker universe coupled to a scalar inflaton field. We consider a three-parameter family of inhomogeneous Cauchy data, for which we can solve analytically the constraint equations.

Loop quantum cosmology and slow roll inflation

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2010
In loop quantum cosmology (LQC) the big bang is replaced by a quantum bounce which is followed by a robust phase of super-inflation. Rather than growing unboundedly in the past, the Hubble parameter vanishes at the bounce and attains a finite universal ...

Inflation and the decaying cosmological constant

Physical Review D, 1992
The interaction of a Higgs field incorporated in the model of a decaying cosmological constant is discussed. This interaction is shown to provide a promising mechanism for sufficient reheating following inflation.

Inflation in an Inhomogeneous Cosmology

1995
We present results on the non-linear dynamics of a wide class of inhomogeneous cosmological models with irrotational dust and vanishing magnetic part of the Weyl tensor, with a cosmological constant Lambda > 0. The study of these models is relevant for the early universe: we find that there are expanding regions that inflate and finally isotropize, i.e.
