On the propagation of gravitational waves in matter-filled Bianchi I universe
Sucheta Datta, Sarbari Guha, Samarjit Chakraborty
In this paper we apply the Regge-Wheeler formalism to study the propagation of axial and polar gravitational waves in matter-filled Bianchi I universe. Assuming that the expansion…
How appropriate are the gravitational entropy proposals for traversable wormholes?
Samarjit Chakraborty, Sarbari Guha, Rituparno Goswami
In this paper we have examined the validity of some proposed definitions of gravitational entropy (GE) in the context of traversable wormhole solutions of the Einstein field equati…
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…
