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…
Dissipative Dark Energy can explain the DESI phantom crossing
Prolay Chanda, Subinoy Das, Suratna Das
DESI results preferring an evolving dark energy component that appears to cross the phantom-divide in the recent past has raised a lot of interest in exploring the nature of dark e…
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…
Resurrecting Vanilla Power Law Inflation with the aid of Continuous Spontaneous Localization in the ACT era
Suratna Das
The Vanilla Power Law Inflation is plagued with two severe drawbacks, the one being the issue of graceful exit, and the other being its compatibility with the existing data. There'…
Behaviour of -attractors in Warm Inflation
Dibya Chakraborty, Suratna Das
The -attractor models of inflation have remained one of the preferred inflationary models for nearly a decade now. The unique attractor nature of these models in the pla…
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…
