Spinning strings, cosmic dislocations and chronology protection
Vitorio A. De Lorenci, Edisom S. Moreira
A massless scalar field is quantized in the background of a spinning string with cosmic dislocation. By increasing the spin density toward the dislocation parameter, a region conta…

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…
