An investigation on gravitational entropy of cosmological models
Samarjit Chakraborty, Sarbari Guha, Rituparno Goswami
In this paper, we investigate the entropy of the free gravitational field for a given epoch for some well-known isotropic and anisotropic cosmologies. We use the definition of grav…
On the gravitational entropy of accelerating black holes
Sarbari Guha, Samarjit Chakraborty
In this paper we have examined the validity of a proposed definition of gravitational entropy in the context of accelerating black hole solutions of the Einstein field equations, w…
Evolution of FRW universe in variable modified Chaplygin gas model
Samarjit Chakraborty, Sarbari Guha, D. Panigrahi
In this paper we study the evolution of the FRW universe filled with variable modified Chaplygin gas (VMCG). We begin with a thermodynamical treatment of VMCG described by the equa…
