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…
