Twirling, whirling, and tensioning: Plectoneme formation and suppression in flexible filaments
A high-aspect ratio flexible filament suspended in a viscous fluid is unstable to a symmetry-breaking whirling motion when axially rotated beyond a critical velocity. We present experiments of this behavior and uncover a rich diversity of plectoneme formation soon after the initial instability, incl...
