NMR Response of a Vortex Tangle in Rotating 3He-B
Abstract
Following the injection of vortex loops into an originally vortex-free sample of superfluid 3He-B at T < 0.6Tc, transient states appear which exhibit a modified response in transverse NMR experiments when compared with the response from the final equilibrium state of rectilinear vortices. Here we investigate the NMR response of a model state where a random vortex tangle is assumed to be superimposed on the equilibrium vortex state. We show that this model can qualitatively account for the experimental findings, provided that the tangle is anisotropic.
