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…
Particle creation by a massless spin- field in a warped cosmological braneworld scenario
Suman Ghosh
Energy momentum tensor of a quantized massless bulk spin- field in five dimensional warped cosmological spacetimes is studied. The four dimensional part of our model r…
Renormalized stress tensor of a quantized massless scalar field in warped cosmological braneworld background
Suman Ghosh
Energy momentum tensor of a conformally coupled quantum scalar field in five dimensional warped cosmological spacetimes is studied. We look at situations where the four dimensional…
