Scalar-tensor cosmologies in a minisuperspace formulation: a case study

  title={Scalar-tensor cosmologies in a minisuperspace formulation: a case study},
  author={Andrzej Borowiec and Aleksander Kozak},
We revisit a general minisuperspace (MSS) formalism for scalar tensor (ST) FLRW type cosmological models in arbitrary frame with perfect fluid source. We discuss how to impose Cauchy data on the corresponding dynamical system in order to reconstruct standard (ΛCDM) cosmological model. So far, the integrability of such models has been extensively studied in the Einstein or Jordan frames mainly. We extend these studies to arbitrary frame taking into account non-minimal coupling between matter and…

Hybrid Metric-Palatini Gravity: Regular Stringlike Configurations
We discuss static, cylindrically symmetric vacuum solutions of hybrid metric-Palatini gravity (HMPG), a recently proposed theory that has been shown to successfully pass the local observational tests
Dynamical analysis in scalar field cosmology
We give a general method to find exact cosmological solutions for scalar-field dark energy in the presence of perfect fluids. We use the existence of invariant transformations for the Wheeler De Witt
Scalar tensor gravity and quintessence
Scalar fields with inverse power-law effective potentials may provide a negative pressure component to the energy density of the universe today, as required by cosmological observations. In order to
Classical and Quantum Solutions in Brans-Dicke Cosmology with a Perfect Fluid
We consider the application of group invariant transformations in order to constrain a flat isotropic and homogeneous cosmological model, containing of a Brans-Dicke scalar field and a perfect fluid
Frame-dependence of higher-order inflationary observables in scalar-tensor theories
In the context of scalar-tensor theories of gravity we compute the third-order corrected spectral indices in the slow-roll approximation. The calculation is carried out by employing the Green's
Selection rules for the Wheeler-DeWitt equation in quantum cosmology
The incompleteness of the Dirac quantization scheme leads to a redundant set of solutions of the Wheeler-DeWitt equation for the wave function in the superspace of quantum cosmology. The selection of
Higgs inflation in the Palatini formulation with kinetic terms for the metric
We consider scalar field inflation in the Palatini formulation of general relativity. The covariant derivative of the metric is then non-zero. From the effective theory point of view it should couple
