Conserved cosmological perturbations in USR inflation and bouncing scenarios
Rathul Nath Raveendran
Inflationary and bouncing scenarios are two frameworks that provide the mechanism to overcome the horizon problem as well as generate the primordial perturbations. In this work, we…
Mimicking two field inflationary features with a single field
Anvy Moly Tom, Rathul Nath Raveendran
It is well known that damped superimposed oscillations at large scales in the primordial power spectrum can be generated in both single field and two field models. In single field…
Amplifying quantum discord during inflationary magnetogenesis through violation of parity
Sagarika Tripathy, Rathul Nath Raveendran, Krishnamohan Parattu +1
It is well known that, during inflation, the conformal invariance of the electromagnetic action has to be broken in order to produce magnetic fields of observed strengths today. Of…
Distinguishing cosmological models through quantum signatures of primordial perturbations
Rathul Nath Raveendran, Sumanta Chakraborty
We study the evolution of various measures of quantumness of the curvature perturbation by integrating out the inaccessible entropic fluctuations in the multi-field models of infla…
