Non-adiabatic transitions in a massless scalar field
Non-adiabatic transitions massless scalar field Mathematical Physics
2012/4/17
We consider the dynamics of a massless scalar field with time-dependent sources in the adiabatic limit. This is an example of an adiabatic problem without spectral gap. The main goal of our paper is t...
Unified Dark Matter scalar field models with fast transition
Unified Dark Matter scalar field fast transition
2010/12/22
We investigate the general properties of Unified Dark Matter (UDM) scalar
field models with Lagrangians with a non-canonical kinetic term, looking specifically for
models that can produce a fast tra...
Consistency of Equations for the Single Scalar Field Case in Second-order Gauge-invariant Cosmological Perturbation Theory
Single Scalar Field Case Cosmological Perturbation Theory
2010/3/18
We derived the second-order perturbations of the Einstein equations and the Klein-Gordon equation for a generic situation in terms of gauge-invariant variables. The consistency of all the equations is...

Chaos in Closed Isotropic Cosmological Models with Steep Scalar Field Potential
Closed Isotropic Cosmological Steep Scalar Field Potential
2010/4/15
The dynamics of closed scalar field FRW cosmological models is studied for several types of exponentially and more than exponentially steep potentials. The parameters of scalar field potentials which ...
