Non-perturbative stabilization of two Kähler moduli in type-IIB/F theory and the inflaton potential
Abhijit Let, Arunoday Sarkar, Chitrak Sarkar +1
We consider a combination of perturbative and non-perturbative corrections in Kähler moduli stabilizations in the configuration of three magnetised intersecting D7 branes in the ty…
Constraining an Early Dark Energy Motivated Quintessential -Attractor Inflaton Potential
Arunoday Sarkar, Buddhadeb Ghosh
We construct a new model of quintessential attractor inflation in conjunction with the features of non-oscillating early dark energy (EDE). Slow-roll plateau of this model is o…
Constraining the quintessential -attractor inflation through dynamical horizon exit method
Arunoday Sarkar, Buddhadeb Ghosh
In the present paper, we perform a sub-Planckian quantum mode analysis of linear cosmological perturbation in the inflaton field over a classical quasi de-Siter metric background b…
Can breakdown of perturbation in the -attractor inflation lead to PBH formation?
Chitrak Sarkar, Arunoday Sarkar, Basundhara Ghosh +1
With the basic -attractor potentials, we investigate an inflationary regime in the high- limit, where the cosmological perturbation breaks down due to large enhancement in th…
A novel way of constraining the -attractor chaotic inflation through Planck data
Arunoday Sarkar, Chitrak Sarkar, Buddhadeb Ghosh
Defining a scale of -modes of the quantum fluctuations during inflation through the dynamical horizon crossing condition we go from the physical variable to var…
Mode analysis of cosmological perturbations with the -model -attractor inflaton potentials
Arunoday Sarkar, Chitrak Sarkar, Buddhadeb Ghosh
We have carried out detailed -mode analysis of single-inflaton slow-roll inflationary perturbations including quantum fluctuations by setting up non-linear coupled differential…
