Vacuum stress around a topological defect

V. A. De Lorenci, E. S. Moreira

We show that a dispiration (a disclination plus a screw dislocation) polarizes the vacuum of a scalar field giving rise to an energy momentum tensor which, as seen from a local ine…

Renormalized scalar propagator around a dispiration

V. A. De Lorenci, E. S. Moreira

The renormalized Feynman propagator for a scalar field in the background of a cosmic dispiration (a disclination plus a screw dislocation) is derived, opening a window to investiga…
