Thermal evolution and stability analysis of phenomenologically emergent dark energy model
Rosemin John, Sarath N., Titus K. Mathew
The phenomenologically emergent dark energy (PEDE) model is a varying dark energy model with no extra degrees of freedom proposed by Li and Shafieloo\citep{Li_2019} to alleviate th…

Running vacuum cosmology with bulk viscous matter
Sarath N, Jerin Mohan N D, Titus K Mathew
We study the late acceleration of the universe by incorporating bulk viscous matter with the running vacuum. The vacuum energy density varies as the squares of the Hubble parameter…

Decaying vacuum and evolution from early inflation to late acceleration
Sarath N, Titus K. Mathew
Decaying vacuum models are a class of models that incorporate the vacuum energy density as a time-evolving entity that has the potential to explain the entire evolutionary history…
