Growth of a single vortex line of 3He-A in a narrow cylinder under rotation

We have studied a single vortex in superfluid 3He-A in a single narrow cylinder under rotation. The diameter of the cylinder is 230 μm. We observed the growth of a single vortex line in the cylinder by rotation. The vortex line grows along the cylinder when the rotation speeds are linearly accelerat...

Zusammenfassung:We have studied a single vortex in superfluid 3He-A in a single narrow cylinder under rotation. The diameter of the cylinder is 230 μm. We observed the growth of a single vortex line in the cylinder by rotation. The vortex line grows along the cylinder when the rotation speeds are linearly accelerated above a critical velocity, which are about 4 (rad/sec).
