Morphology of Inflationary Gravitational Wave Spectra imprinted by a Sequence of Post-Inflationary Epochs
Swagat S. Mishra, Athul K. Soman
The expansion history of the Universe prior to Big Bang Nucleosynthesis (BBN) remains largely unconstrained. The high-energy post-inflationary era may involve multiple distinct epo…
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…
Braneworld Dark Energy in light of DESI DR2
Swagat S. Mishra, William L. Matthewson, Varun Sahni +2
Recent observational results from the DESI collaboration reveal tensions with the standard CDM model and favour a scenario in which dark energy (DE) decays over time. The DESI D…
