Warm Inflation in gravity
Tuhina Ghorui, Prabir Rudra, Farook Rahaman +1
We investigate warm inflation in the framework of gravity within a Friedmann-Robertson-Walker spacetime. Unlike cold inflation, where the inflaton evolves in isolation, warm…

Some New Types of Well-Behaved Polynomial Redshift Parametrization of Dark Energy Equation of State
Prabir Rudra, Aritra Sanyal, Promila Biswas +3
In this paper, we explore a new type of smooth and well-behaved polynomial redshift function that can avoid a future singularity. Using this function, we have proposed different re…

Godel Universe in gravity: Exploring causality violation and closed time-like curves
Tuhina Ghorui, Prabir Rudra, Farook Rahaman
In this work, the classical Godel solution from general relativity is extended into the framework of modified gravity theories based on non-metricity and the trace of the energ…
