Stressenergy of a quantized scalar field in static wormhole spacetimes
Abstract
An analytical approximation of <T_{μν}> for a quantized scalar field in a static spherically symmetric spacetime with a topology S^{2}×R^{2} is obtained. The gravitational background is assumed slowly varying. The scalar field is assumed to be both massive and massless, with an arbitrary coupling ξ to the scalar curvature and in a zero temperature vacuum state. It is demonstrated that for some values of curvature coupling the stressenergy has the properties needed to support the wormhole geometry.
