Vacuum-polarization effects in global monopole space-times
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 ex...
