Quantum resolution of the Schwarzschild singularity
Vishnulal Cheriyodathillathu, Tanmay Patil, Saurya Das +1
We revisit the Schwarzschild singularity in a semiclassical setting where the background geometry is classical and quantum effects enter through Bohmian (quantal) trajectories asso…

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…
