Vacuum polarization for a spinor massive field in an Einstein-Maxwell spacetime |
Abstract _ |
We find the contribution to the vacuum expectation value of the energy-momentum tensor of a massive Dirac field due to the gravitational field produced by a cylinder of matter with an interior magnetic field (Safko-Witten spacetime) and show the dependence of this quantity with the content of matter and the magnetic field. |
