Study of Thermodynamic Quantities in Generalized Gravity Theories
Surajit Chattopadhyay, Ujjal Debnath, Samarpita Bhattacharya
In this work, we have studied the thermodynamic quantities like temperature of the universe, heat capacity and squared speed of sound in generalized gravity theories like Brans-Dic…
Study of Thermodynamics in Generalized Holographic and Ricci Dark Energy Models
Samarpita Bhattacharya, Ujjal Debnath
We have considered the flat FRW model of the universe which is filled with the combination of dark matter and dark energy. Here we have considered two types of dark energy models:…
Thermodynamics of Modified Chaplygin Gas and Tachyonic Field
Samarpita Bhattacharya, Ujjal Debnath
Here we generalize the results of the work of ref. [10] in modified Chaplygin gas model and tachyonic field model. Here we have studied the thermodynamical behaviour and the equati…
Validity of Thermodynamical Laws in Dark Energy Filled Universe
Samarpita Bhattacharya, Ujjal Debnath
We have considered the flat FRW model of the universe which is filled with only dark energy. The general descriptions of first and second laws of thermodynamics are investigated on…
Brans-Dicke Theory and Thermodynamical Laws on Apparent and Event Horizons
Samarpita Bhattacharya, Ujjal Debnath
In this work, we have described the Brans-Dicke theory of gravity and given a particular solution by choosing a power law form of scalar field and constant . If we assume fi…
Thermodynamical Laws in Horava-Lifshitz Gravity
Samarpita Bhattacharya, Ujjal Debnath
In this work, we have investigated the validity of GSL of thermodynamics in a universe (open, closed and flat) governed by Hoava-Lifshitz gravity. If the universe…
