Christian Stephan-Otto, Ken D. Olum, Xavier Siemens
We investigate the effects of cosmological expansion on the spectrum of small-scale structure on a cosmic string. We simulate the evolution of a string with two modes that differ i…

Cosmic String Cusps with Small-Scale Structure: Their Forms and Gravitational Waveforms
Xavier Siemens, Ken D. Olum
We present a method for the introduction of small-scale structure into strings constructed from products of rotation matrices. We use this method to illustrate a range of possibili…
