Gravitational Baryogenesis: Problems and Possible Resolution

E. Arbuzova, A. Dolgov, K. Dutta +1

The coupling of baryonic current to the derivative of the curvature scalar, , inherent to gravitational baryogenesis (GBG), leads to a fourth order differential equation of moti…

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…

Effective chemical potential in spontaneous baryogenesis

Arnab Dasgupta, Rajeev Kumar Jain, Raghavan Rangarajan

Models of spontaneous baryogenesis have an interaction term in the Lagrangian, where is the baryonic current and can be a pseudo-Nambu-Goldstone boso…

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…
