Geodesic Congruences in 5D Warped Ellis-Bronnikov Spacetimes
Vivek Sharma, Suman Ghosh
We study the timelike geodesic congruences in the generalized Ellis-Bronnikov spacetime (4D-GEB) and in recently proposed 5D model where a 4D-GEB is embedded in a warped geometry (…
Geodesics in Generalised Ellis-Bronnikov Spacetime Embedded in Warped 5D Background
Vivek Sharma, Suman Ghosh
We study the particle trajectories in the recently proposed five dimensional warped (generalized) Ellis-Bronnikov spacetime (5D-WGEB) (which does not require exotic matter) as well…
Generalised Ellis-Bronnikov wormholes embedded in warped braneworld background and energy conditions
Vivek Sharma, Suman Ghosh
Ellis-Bronnikov (EB) wormholes require violation of null energy conditions at the `throat'. This problem was cured by a simple modification of the `shape function', which introduce…
Octonionic Gravi-electromagnetism and Dark Matter
B. C. Chanyal, V. K. Sharma, O. P. S. Negi
An attempt has been made to analyse the the role of octonions in various unified field theories associated with dyons and the dark matter. Starting with the split octonion al- gebr…
