On signatures of spontaneous collapse dynamics modified single field inflation
Shreya Banerjee, Suratna Das, K. Sravan Kumar +1
The observed classicality of primordial perturbations, despite their quantum origin during inflation, calls for a mechanism for quantum-to-classical transition of these initial flu…
Interacting 3-form dark energy models: distinguishing interactions and avoiding the Little Sibling of the Big Rip
João Morais, Mariam Bouhmadi-López, K. Sravan Kumar +2
In this paper we consider 3-form dark energy (DE) models with interactions in the dark sector. We aim to distinguish the phenomenological interactions that are defined through the…
Non-Gaussianity in multiple three-form field inflation
K. Sravan Kumar, David J. Mulryne, Nelson J. Nunes +2
In this work, we present a method for implementing the formalism to study the primordial non-Gaussianity produced in multiple three-form field inflation. Using a dual descript…
-essence model from the mechanical approach point of view: coupled scalar field and the late cosmic acceleration
Mariam Bouhmadi-López, K. Sravan Kumar, João Marto +2
In this paper, we consider the Universe at the late stage of its evolution and deep inside the cell of uniformity. At these scales, we can consider the Universe to be filled with d…
