Gravitational backreaction simulations of simple cosmic string loops

Understand

We present the results of computational gravitational backreaction on simple models of cosmic string loops.

• These results give us insight into the general behavior of cusps and kinks on loops, in addition to other features of evolution.
• Kinks are rounded off via an asymmetric and divergent correction to the string direction.
• The result is that cusps emerge in the place of kinks but the resulting smooth string section has a small amount of energy.
