Wormholes supported by Scalar Fields with Negative Kinetic Energy
F. Rahaman, M. Kalam, K. A. Rahman
We provide a new model of higher dimensional wormholes supported by phantom energy derived from a scalar field with negative kinetic term. We have shown that the Averaged Null Ener…
Discussion on some characteristics of the Charged Brane-world Black holes
M. Kalam, F. Rahaman, A. Ghosh +1
Several physical natures of charged brane-world black holes have been investigated. At first, time-like and null geodesics of the charged brane-world black holes are presented. We…
Cosmic coincidence problem and variable constants of physics
Mubasher Jamil, Farook Rahaman, Mehedi Kalam
The standard model of cosmology is investigated using time dependent cosmological constant and Newton's gravitational constant . The total energy content is described by the…
Wormhole geometry from real feasible matter sources
F. Rahaman, M. Kalam, K. A. Rahman
We provide a prescription of real feasible sources that supply fuel to construct a traversable wormhole. A class of exact solutions for Einstein-Maxwell field equations describing…
Generalised scalar-tensor theory and the cosmic acceleration
Narayan Banerjee, Koyel Ganguly
In this paper it has been shown that a simple functional form of in a generalised scalar tensor theory can drive the present cosmic acceleration without any quintessence fie…
Gravitational field of domain wall in Lyra geometry
F. Rahaman, P. Ghosh
In this paper, we study the domain wall with time dependent displacement vectors based on Lyra geometry in normal gauge i.e. displacement vector . The field…
