Some Classes of Interacting Two-Fluid Model of the Expanding Universe
Subhra Bhattacharya
We consider interacting dark matter-dark energy models arising out of a general interaction term Here is a functional relation connectin…
Complexity factor Parametrization for Traversable Wormholes
Subhra Bhattacharya, Subhasis Nalui
It is known that static traversable wormhole in Einstein gravity is supported by matter that violates null energy conditions (NEC). Essentially such wormhole will be characterised…
Revisiting Barrow's Graduated Inflationary Universe: A Warm perspective
Subhra Bhattacharya
It is presumed that thermal fluctuations present during inflationary epoch can make inflaton scalar field to interact with other fields resulting in the existence of a thermal comp…
Mimicking the CDM Universe through inhomogeneous space-time
Subhra Bhattacharya
Starting from an inhomogeneous space-time model of the universe we could recreate a scenario of recent time accelerating universe dominated by Dark Energy type of fluid. The backgr…
Revisiting the Evolving Lorentzian Wormhole: a General Perspective
Subhra Bhattacharya, Tanwi Bandyopadhyay
Wormholes can be described as geometrical structures in space and time that can serve as connection between distant regions of the universe. Mathematically, general wormholes can b…
Spherically symmetric wormhole solutions in a general anisotropic matter field
Shibaji Halder, Subhra Bhattacharya, Subenoy Chakraborty
The present work is an attempt to find possible traversable wormhole solutions in static spherically symmetric space-time supported by anisotropic matter field. Part of the work co…
