Dark Matter as an Inflationary Relic in Warm Inflation
Swagat S. Mishra, Umang Kumar, Suratna Das +1
Warm inflation is usually expected to completely deplete the inflaton condensate by dissipating its energy into radiation. We show that this expectation fails in a simple and obser…

Eigenvalue formulation of Stochastic Inflation and application to large perturbation generating inflationary features
Swagat S. Mishra, Edmund J. Copeland, Anne M. Green
Stochastic inflation is a powerful technique for calculating the probability distribution function (PDF) of large inflationary perturbations, which may collapse to form Primordial…

Effective Phantom Dark Energy: What Cosmological Reconstruction Does and Does Not Imply
Swagat S. Mishra
In observational cosmology, the dark energy density and equation of state are effective quantities reconstructed at the background level under a set of assumptions. These include t…
