Non-local $R^{2}$ -like inflation, Gravitational Waves and Non-Gaussianities

K. Sravan Kumar

The emergence of $R^{2}$ (Starobinsky) inflation from the semi-classical modification of gravity due to matter quantum fields (trace anomaly) clearly points out the importance of fun…

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…
