The paradigm of warm quintessential inflation and spontaneous baryogenesis
Soumen Basak, Sukannya Bhattacharya, Mayukh R. Gangopadhyay +3
In this paper, we consider a scenario of spontaneous baryogenesis in a framework of warm quintessential inflation where the residual inflaton field, left out after warm inflation,…
Study of warm inflationary models and their parameter estimation from CMB
Richa Arya, Raghavan Rangarajan
Observations of the temperature anisotropies in the Cosmic Microwave Background (CMB) radiation show that the models of inflation with the monomial potentials are inconsistent with…
A plausible solution to the problem of initial conditions for inflation
Suratna Das, Raghavan Rangarajan
We propose yet another solution to the initial condition problem of inflation associated with homogeneity beyond the horizon at the onset of inflation, in cases where inflation is…
Current Status of Warm Inflation
Raghavan Rangarajan
Warm inflation is an inflationary scenario in which a thermal bath coexists with the inflaton during inflation. This is unlike standard cold inflation in which the Universe is effe…
Revisiting CMB constraints on Warm Inflation
Richa Arya, Arnab Dasgupta, Gaurav Goswami +2
We revisit the constraints that Planck 2015 temperature, polarization and lensing data impose on the parameters of warm inflation. To this end, we study warm inflation driven by a…
Gravitino production in a thermal Universe revisited
Richa Arya, Namit Mahajan, Raghavan Rangarajan
We study the production of spin 1/2 gravitinos in a thermal Universe. Taking into account supersymmetry breaking due to the finite thermal energy density of the Universe, there is…
