Oscillatory dark energy with phantom crossings in Einstein-Gauss-Bonnet gravity
Saddam Hussain, Sandip Biswas
Recent baryon acoustic oscillation measurements from the Dark Energy Spectroscopic Instrument (DESI), combined with supernova observations, show a mild preference for an evolving d…
Constant-Roll Inflation as a Competitive Alternative to Slow-Roll Inflation
Sandip Biswas, Rajib Saha, Kaushik Bhattacharya
Starting from the constant-roll condition, which involves the constant-roll parameter , which is a fundamental constant in the constant-roll inflationary models, we derive the s…
Dynamical systems approach to Cold and Warm Inflation within slow-roll and beyond
Sandip Biswas, Saddam Hussain, Kaushik Bhattacharya
In this work, we systematically present a new dynamical systems approach to standard inflationary processes and their variants as constant-roll inflation. Using the techniques pres…
Reassessing constant-roll Warm Inflation
Sandip Biswas, Kaushik Bhattacharya, Suratna Das
Departing from standard slow-roll conditions is one way of putting the inflationary paradigm to test, and constraining the dynamics of the inflaton field with a constant-rate of ro…
Embedding Ultra slow-roll inflaton dynamics in Warm Inflation
Sandip Biswas, Kaushik Bhattacharya, Suratna Das
Slow-roll of the inflaton field defines the standard dynamics of the inflationary epoch. However, the inflationary system deviates from slow-roll when it encounters an extremely fl…
