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…
Stability analysis of warm quintessential dark energy model
Suratna Das, Saddam Hussain, Debottam Nandi +2
A dynamical system analysis is performed for a model of dissipative quintessential inflation realizing warm inflation at early primordial times and dissipative interations in the d…
Running and running of the running of the scalar spectral index in warm inflation
Suratna Das, Rudnei O. Ramos
Next generation of cosmological observations are expected to improve the measurements of several quantities connected to the primordial inflation in the early Universe. These quant…
Runaway potentials in warm inflation satisfying the swampland conjectures
Suratna Das, Rudnei O. Ramos
The runaway potentials, which do not possess any critical points, are viable potentials which befit the recently proposed de Sitter swampland conjecture very well. In this work, we…
Lowering tensor-to-scalar ratio by pre-inflationary dynamics
Suratna Das
Pre-inflationary dynamics is known to have left observable imprints via the varied dynamics of the inflaton and the graviton fields during those epochs. It is highlighted here that…
