Abstract: We present analytical studies of gravitational and electromagnetic
backreaction on cosmic strings. 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 ... read moreshould 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.
