摘要：
Vacuum quantum effects in a conformally coupled scalar field on the background of a conformally flat geometry of brane worlds are studied. Based on the corresponding results for a Minkowski space-time in the general case of mixed boundary conditions on the branes, formulas are derived for the vacuum averaged energy-momentum tensor and for the vacuum forces acting on the boundaries. The important special case of AdS background is examined and applications to the Randall-Sundrum model are discussed. The possible stabilization of the radion by vacuum forces is demonstrated.
