Renormalized stress tensor of a quantized massless scalar field in warped cosmological braneworld background
Abstract 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 part represents a cosmological thick brane and the scale of the extra dimension is time dependent. Renormaliza...
