AdS backgrounds and induced gravity
Hai Lin, Gaurav Narain
In this paper we look for AdS solutions to generalised gravity theories in the bulk in various spacetime dimensions. The bulk gravity action includes the action of a non-minimally…
Ultraviolet complete dark energy model
Gaurav Narain, Tianjun Li
We consider a local phenomenological model to explain a non-local gravity scenario which has been proposed to address dark energy issues. This non-local gravity action has been see…
On the Renormalization Group perspective of -attractors
Gaurav Narain
In this short paper we outline a recipe for the reconstruction of gravity starting from single field inflationary potentials in the Einstein frame. For simple potentials one…
Signs and Stability in Higher-Derivative Gravity
Gaurav Narain
Perturbatively renormalizable higher-derivative gravity in four space-time dimensions with arbitrary signs of couplings has been considered. Systematic analysis of the action with…
