Critical Velocity of Vortex Nucleation in Rotating Superfluid 3He-A
V. M. H. Ruutu, J. Kopu, M. Krusius +4
We have measured the critical velocity v_c at which 3He-A in a rotating cylinder becomes unstable against the formation of quantized vortex lines with continuous (singularity-free)…

Big bang simulation in superfluid 3He-B -- Vortex nucleation in neutron-irradiated superflow
V. M. H. Ruutu, V. B. Eltsov, A. J. Gill +6
We report the observation of vortex formation upon the absorption of a thermal neutron in a rotating container of superfluid He-B. The nuclear reaction n + He = p + H +…
