Stress-energy tensor for a quantised bulk scalar field in the Randall-Sundrum brane model
arXiv:hep-th/0309176 · doi:10.1103/PhysRevD.69.044023
Abstract
We calculate the vacuum expectation value of the stress-energy tensor for a quantised bulk scalar field in the Randall-Sundrum model, and discuss the consequences of its local behaviour for the self-consistency of the model. We find that, in general, the stress-energy tensor diverges in the vicinity of the branes. Our main conclusion is that the stress-energy tensor is sufficiently complicated that it has implications for the effective potential, or radion stabilisation, methods that have so far been used.
