Vacuum polarization near cosmic string in RS2 brane world
Yuri Grats, Anton Rossikhin
Abstract
Gravitational field of cosmic strings in theories with extra spatial dimensions must differ significantly from that in the Einstein's theory. This means that all gravity induced properties of cosmic strings need to be revised too. Here we consider the effect of vacuum polarization outside a straight infinitely thin cosmic string embedded in a RS2 brane world. Perturbation technique combined with the method of dimensional regularization is used to calculate < Tμν >vacren for a massless scalar field.
