Abstract:
The gravitational effect produced by a global monopole may be approximated by a solid deficit angle. As a consequence, the energy-momentum tensor of a quantum field will have a nonzero vacuum expectation value. Here we study this "vacuum-polarization effect" around the monopole. We find explicit expressions for both 2ren and Tren for a massless scalar field. The back reaction of the quantum field on the monopole metric is also investigated. © 1991 The American Physical Society.
