Hamilton-Jacobi formalism for Generalized Chaplygin Gas models

  title={Hamilton-Jacobi formalism for Generalized Chaplygin Gas models},
  author={Yordan Ignatov and Mauro Pieroni},
In this work we discuss the application of the Hamilton-Jacobi formalism on the scalar field implementation of Generalized Chaplygin Gas models. This corresponds to a Generalised Born-Infeld action for the scalar field, which in an initial fast-rolling phase mimics a matter-like behavior and in the final slow-rolling phase mimics a cosmological constant. In order to enrich the phenomenology of the model, we add an extra functional freedom, specified through a scalar potential for the field…

From k-essence to generalised Galileons
We determine the most general scalar field theories which have an action that depends on derivatives of order two or less, and have equations of motion that stay second order and lower on flat
Gauge-invariant analysis of perturbations in Chaplygin gas unified models of dark matter and dark energy
We exploit the gauge-invariant formalism to analyse the perturbative behaviour of two cosmological models based on the generalized Chaplygin gas describing both dark matter and dark energy in the
Scalar speed limits and cosmology: Acceleration from D-cceleration
Causality on the gravity side of the AdS/CFT correspondence restricts motion on the moduli space of the N = 4 super Yang Mills theory by imposing a speed limit on how fast the scalar field may roll.
Does Chaplygin gas have salvation?
We investigate the unification scenario provided by the generalized Chaplygin gas model (a perfect fluid characterized by an equation of state p=−A/ρα). Our concerns lie with a possible tension

It is argued that a number of models in which the energy density of the scalar field red-shifts in a specific manner are studied could reconcile the low dynamical estimates of the mean mass density with the negligibly small spatial curvature preferred by inflation.
Scalar-tensor gravity in an accelerating universe
We consider scalar-tensor theories of gravity in an accelerating universe. The equations for the background evolution and the perturbations are given in full generality for any parametrization of the
Does a generalized Chaplygin gas correctly describe the cosmological dark sector
Abstract Yes, but only for a parameter value that makes it almost coincide with the standard model. We reconsider the cosmological dynamics of a generalized Chaplygin gas (gCg) which is split into a
Kinetically driven quintessence
Abstract Recently, a novel class of models for inflation has been found in which theinflationary dynamics is driven solely by (non-canonical) kinetic terms ratherthan by potential terms. As an obvious
Curvature Quintessence
The issues of quintessence and cosmic acceleration can be discussed in the framework of higher order theories of gravity. We can define effective pressure and energy density directly connected to the
Generalized G-Inflation —Inflation with the Most General Second-Order Field Equations—
We study generalized Galileons as a framework to develop the most general single-field inflation models ever, Generalized G-inflation, containing yet further generalization of Ginf lation, as well as
