Show affiliationsThe gravitational back-reaction is calculated for the conformally invariant scalar field within a black cosmic string interior with cosmological constant. Using the perturbed metric, the gravitational effects of the quantum field are calculated. It is found that near the horizon, the perturbations initially strengthen the singularity. This effect is similar to the case of spherical symmetry (without a cosmological constant). This indicates that the behaviour of quantum effects may be universal and not dependent on the geometry of the spacetime or the presence of a non-zero cosmological constant.
