Abstract
We study the behavior of vortex filaments subject to a uniform density of phase twist in oscillatory media described by the complex Ginzburg -Landau equation. The first instability is a supercritical Hopf bifurc ation to stable propagating helical vortices. The secondary instabilit y, also a forward Hopf bifurcation, leads to quasiperiodic supercoiled filaments. dynamical objects are akin to those of twisted elastic rod s.
