Fields due to kinky, cuspless, cosmic loops

We study the gravitational field of a kinky, cuspless loop of cosmic string. The gravitational field does not have a repulsive component as in the case of loops with cusps and so the gravitational field produced by cuspless loops is spherically symmetric and Newtonian when we go far away from the loop. We also find the electromagnetic field due to kinks on a current-carrying superconducting cosmic loop and the Goldstone field produced by a loop of global string. For the case of the Goldstone field we also consider loops with cusps.
