Inflationary $α$ -Attractor From Type IIB/F Theory

Arunoday Sarkar, Buddhadeb Ghosh

We derive an $α = 1/3$ - attractor potential of slow-roll inflation in the geometric set-up of three intersecting $D 7$ branes under $T^{6} / Z_{N}$ type of $C Y_{3}$ -compactification within t…

Spontaneous baryogenesis and generation of gravitational waves in a new model of quintessential $α$ -attractor

Arunoday Sarkar, Buddhadeb Ghosh

We study the role of $α$ -parameter of the newly proposed model of quintessential $α$ -attractor inflation (arXiv: 2305.00230 [gr-qc]) to the case of quintessential spontaneous baryo…

Mode analysis of cosmological perturbations with the $E$ -model $α$ -attractor inflaton potentials

Arunoday Sarkar, Chitrak Sarkar, Buddhadeb Ghosh

We have carried out detailed $k$ -mode analysis of single-inflaton slow-roll inflationary perturbations including quantum fluctuations by setting up non-linear coupled differential…
