THE TENTH MARCEL GROSSMANN MEETING PART A On Recent Developments in Theoretical and Experimental General Relativity, Gravitation

Physics

Scientific paper

The dominant contribution for the renormalized stress tensor of a massless scalar field around a cosmic string with a dislocation was presented recently. By considering this energy-momentum distribution as source of the linearized semiclassical Einstein equations, the first order perturbative solution for the approximated spacetime geometry is derived. The non trivial motion of test particles is discussed, showing that a helical motion is quantum mechanically induced by the presence of the defect.
