Inflationary Gravitational Waves as a probe of the unknown post-inflationary primordial Universe
Athul K. Soman, Swagat S. Mishra, Mohammed Shafi +1
One of the key predictions of the standard inflationary paradigm is the quantum mechanical generation of the transverse and traceless tensor fluctuations due to the rapid accelerat…
Formation and decay of oscillons after inflation in the presence of an external coupling, Part-I: Lattice simulations
Mohammed Shafi, Edmund J. Copeland, Rafid Mahbub +2
We investigate the formation and decay of oscillons during the post-inflationary reheating epoch from inflaton oscillations around asymptotically flat potentials in the pres…
Cosmic Inflation: Background dynamics, Quantum fluctuations and Reheating
Swagat S. Mishra
These lecture notes provide a pedagogical introduction to some aspects of the inflationary cosmology, including the background scalar field dynamics, generation of primordial seed…
New models of Quintessential Inflation featuring plateau and hilltop potentials
Swagat S. Mishra, Varun Sahni
We introduce a new class of hilltop and plateau potentials which can successfully unify inflation and dark energy resulting in Quintessential Inflation (QI). Interestingly these ne…
