Phase diagram of turbulence in superfluid 3He-B

Ferromagneticlike Resonance Behavior in Superfluid 3He-B

Phase diagram of the topological superfluid 3He confined in a nanoscale slab geometry.

The superfluid phases of helium-3 ((3)He) are predicted to be strongly influenced by mesoscopic confinement. However, mapping out the phase diagram in a confined geometry has been experimentally challenging. We confined a sample of (3)He within a nanofluidic cavity of precisely defined geometry, cooled it, and fingerprinted the order parameter using a sensitive nuclear magnetic resonance spectr...

The dynamics of vortex generation in superfluid 3He-B

A profound change occurs in the stability of quantized vortices in externally applied flow of superfluid 3He-B at temperatures . 0.6Tc, owing to the rapidly decreasing damping in vortex motion with decreasing temperature. At low damping an evolving vortex may become unstable and generate a new independent vortex loop. This single-vortex instability is the generic mechanism for creating the requ...

Metastability in decelerating rotation of superfluid 3He-B

The maximum and the equilibrium numbers of vortex lines are measured in a rotating cylindrical container as a function of its rotation velocity X. We find that a slow cool-down through the superfluid transition at constant rotation produces a state with the equilibrium number of lines, N %2 (X). In decelerating rotation, when vortex lines annihilate, the state is obtained which includes the max...
