Nonminimal Derivative Coupling and the Recovering of Cosmological Constant
We show that the existence of the cosmological constant can be connected to a nonminimal derivative coupling, in the action of gravity, between the geometry and the kinetic part of a given scalar field without introducing any effective potential of scalar fields. Exact solutions are given. PACS: 98.80 H, 04.50 +h E-mail:[email protected] E-mail:[email protected]
متن کاملCosmology with Nonminimal Derivative Couplings
We study a theory which generalizes the nonminimal coupling of matter to gravity by including derivative couplings. This leads to several interesting new dynamical phenomena in cosmology. In particular, the range of parameters in which inflationary attractors exist is greatly expanded. We also numerically integrate the field equations and draw the phase space of the model in second order approx...
متن کاملNonminimal coupling, equivalence principle and exact Foldy-Wouthuysen transformation
It is shown that the exact Foldy-Wouthuysen transformation for spin-0 particles on spacetimes described by the metrics ds = V dt −W dx, where V = V (x) and W = W (x), only exists if the scalar field is nonminimally coupled to the Ricci scalar field with a coupling constant equal to 1 6 . The nonminimal coupling term, in turn, does not violate the equivalence principle. As an application we obta...
متن کاملInflation and quintessence with nonminimal coupling
The nonminimal coupling (NMC) of the scalar field to the Ricci curvature is unavoidable in many cosmological scenarios. Inflation and quintessence models based on nonminimally coupled scalar fields are studied, with particular attention to the balance between the scalar potential and the NMC term ξRφ2/2 in the action. NMC makes acceleration of the universe harder to achieve for the usual potent...
متن کاملNew exact solutions for inflationary cosmological perturbations
From a general ansatz for the effective potential of cosmological perturbations we find new, exact solutions in single-scalar-field inflation: A three parameter family of exact solutions that encompasses all exact solutions that have been known previously (power-law inflation, Easther’s model, and a generalized version of Starobinsky’s solution). The main feature of this new family is that the ...
