DSWIM:Efficient and Stable Deterministic Computation of Warm Inflation Perturbations
Umang Kumar
Warm inflation perturbations are sourced by both thermal and quantum fluctuations and are commonly computed through stochastic realizations of the perturbation equations, as implem…
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…
SWIM: Stochastic Warm Inflation Module to generate and analyse Warm Inflationary power spectrum
Umang Kumar, Suratna Das
Numerical analysis to determine the form of the scalar power spectrum in Warm Inflationary paradigm is inevitable. One further needs numerical techniques to analyse any Warm Inflat…
Witten-O'Raifeartaigh potential revisited in the context of Warm Inflation
Suratna Das, Umang Kumar, Swagat S. Mishra +1
Warm Inflation is a scenario in which the inflaton field dissipates its energy during inflation to maintain a subdominant constant radiation bath. Two of its remarkable features ar…
A generalized method of constraining Warm Inflation with CMB data
Umang Kumar, Suratna Das
A thorough MCMC analysis of any inflationary model against the current cosmological data is essential for assessing the validity of such a model as a viable inflationary model. War…
