Stress-energy of a quantized scalar field in static wormhole spacetimes | Arkadii A. Popov
; | Date: |
20 Sep 2001 | Journal: | Phys.Rev. D64 (2001) 104005 | Subject: | hep-th | Abstract: | An analytical approximation of $$ for a quantized scalar field in a static spherically symmetric spacetime with a topology $S^2 imes R^2$ is obtained. The gravitational background is assumed slowly varying. The scalar field is assumed to be both massive and massless, with an arbitrary coupling $xi$ to the scalar curvature and in a zero temperature vacuum state. It is demonstrated that for some values of curvature coupling the stress-energy has the properties needed to support the wormhole geometry. | Source: | arXiv, hep-th/0109166 | Services: | Forum | Review | PDF | Favorites |
