Non-minimal derivative coupling gravity in cosmology

Abstract: We give a brief review of the non-minimal derivative coupling (NMDC) scalar field theory in which there is non-minimal coupling between the scalar field derivative term and the Einstein tensor. We assume that the expansion is of power-law type or super-acceleration type for small redshift. The Lagrangian includes the NMDC term, a free kinetic term, a cosmological constant term and a barotropic matter term. For a value of the coupling constant that is compatible with inflation, we use the combined WMAP9 (WMAP9+… Show more

“…Shortly after, it was discovered that the non-minimal kinetic coupling sector L 5 (called "John" in the "Fab Four" terminology of [24]) leads to an accelerated expansion provided G 5 is constant and G 5X = 0, see e.g. [25][26][27][28][29][30] and references therein. A lot of work was also done in perturbation theory, with the goal of finding potentially observable deviations from GR in large-scale structures and the conditions on the parameter space that avoid too large gravitational instabilities [31].…”
