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…
Swampland, Axions and Minimal Warm Inflation
Suratna Das, Gaurav Goswami, Chethan Krishnan
Warm inflation has been noted previously as a possible way to implement inflationary models compatible with the dS swampland bounds. But often in these discussions the heat bath dy…
Distance, de Sitter and Trans-Planckian Censorship conjectures: the status quo of Warm Inflation
Suratna Das
In this short note, we pointed out that Warm inflationary scenario remains to be favoured over its cold counterpart by the recently proposed conjectures, which aim to overrule de S…
Warm Inflation in the light of Swampland Criteria
Suratna Das
Warm Inflation seems to be the most befitting single-field slow-roll inflation scenario in the context of the recently proposed Swampland Criteria. We investigate the constraints t…
A note on Single-field Inflation and the Swampland Criteria
Suratna Das
The recently proposed Swampland Criteria aim to evade any (meta-)stable de Sitter constructions within String landscapes, making it difficult to accommodate accelerating phases, li…
Lee-Wick radiation induced bouncing universe models
Kaushik Bhattacharya, Yi-Fu Cai, Suratna Das
The present article discusses about the effect of a Lee-Wick partner infested radiation phase of the early universe. As Lee-Wick partners can contribute negative energy density so…
