Thermodynamical Aspects of Some Cosmological Models
Tanima Duary
The research work in the thesis is focused on the thermodynamic analysis of cosmological models, especially the models that explain late-time cosmic acceleration. According to the…
Signature flip in deceleration parameter: A thermodynamic phase transition?
Tanima Duary, Narayan Banerjee, Ananda Dasgupta
Using the Hayward-Kodama temperature for the apparent horizon, it is found that matter content in the Universe is not thermodynamically stable, and the entry to the late accelerate…
Brans-Dicke Cosmology: Thermodynamic viability
Tanima Duary, Narayan Banerjee
Brans-Dicke cosmological models for a spatially isotropic and homogeneous universe are tested in terms of the validity of the Generalized Second Law of Thermodynamics (GSL). The in…
Thawing and Freezing Quintessence Models: A thermodynamic Consideration
Tanima Duary, Ananda Dasgupta Narayan Banerjee
Thawing and freezing quintessence models are compared thermodynamically. Both of them are found to disobey the Generalized Second Law of Thermodynamics. However, for freezing model…
