An anisotropic bouncing universe in non-local gravity
K. Sravan Kumar, Shubham Maheshwari, Anupam Mazumdar +1
We show that it is possible to realize a cosmological bouncing solution in an anisotropic but homogeneous Bianchi-I background in a class of non-local, infinite derivative theories…
Stable, non-singular bouncing universe with only a scalar mode
K. Sravan Kumar, Shubham Maheshwari, Anupam Mazumdar +1
In this paper, we study a class of higher derivative, non-local gravity which admits homogeneous and isotropic non-singular, bouncing universes in the absence of matter. At the lin…
Perturbations in higher derivative gravity beyond maximally symmetric spacetimes
K. Sravan Kumar, Shubham Maheshwari, Anupam Mazumdar
We study (covariant) scalar-vector-tensor (SVT) perturbations of infinite derivative gravity (IDG), at the quadratic level of the action, around conformally-flat, covariantly const…
Non-singular metric for an electrically charged point-source in ghost-free infinite derivative gravity
Luca Buoninfante, Gerhard Harmsen, Shubham Maheshwari +1
In this paper we will construct a linearized metric solution for an electrically charged system in a {\it ghost-free} infinite derivative theory of gravity which is valid in the en…
