For oscillating loops of cosmic string, we present a general argument for how kinks must change; additionally, we apply this general argument to the geometrically simple case of the Garfinkle-Vachaspati loop. Our results suggest that the formation of cusps on loops is delayed, and so we should expect fewer cuspy signatures to be seen in gravitational wave observations. Electromagnetic backreaction we show to reduce currents on a string at least as rapidly as necessary to avoid a paradox, and currents induced on a superconducting straight string will be asymptotically reduced to zero.; Thesis (Ph.D.)--Tufts University, 2017.; Submitted to the Dept. of Physics.; Advisor: Kenneth Olum.; Committee: Alexander Vilenkin, Lawrence Ford, Jose Blanco-Pillado, Timothy Atherton, and Kenneth Olum.; Keyword: Physics. %[ 2022-10-11 %9 Text %~ Tufts Digital Library %W Institution
