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…
Analytic infinite derivative gravity, -like inflation, quantum gravity and CMB
Alexey S. Koshelev, K. Sravan Kumar, Alexei A. Starobinsky
Emergence of inflation which is the best fit framework for CMB observations till date comes from the attempts to attack the problem of quantization of gravity which in turn h…
Dark matter and Standard Model reheating from conformal GUT inflation
Simone Biondini, K. Sravan Kumar
Spontaneous breaking of conformal symmetry has been widely exploited in successful model building of both inflationary cosmology and particle physics phenomenology. Conformal Grand…
Non-Gaussianities and tensor-to-scalar ratio in non-local -like inflation
Alexey S. Koshelev, K. Sravan Kumar, Anupam Mazumdar +1
In this paper we will study -like inflation in a non-local modification of gravity which contains quadratic in Ricci scalar and Weyl tensor terms with analytic infinite deriva…
