Vortex formation and annihilation in rotating superfluid 3He-B at low temperatures
V.B. Eltsov, R. de Graaf, P.J. Heikkinen, J.J. Hosio, R. Hänninen, M. KrusiusIn superfluid 3He-B the damping of vortex motion varies many orders of magnitude in the currently accessible temperature range from Tc to below 0.2 Tc. The large variation in the dynamics switches on sequentially different processes of vortex formation as a function of temperature. These can be examined in a smooth-walled rotating cylinder in the absence of surface pinning. We provide an overview of vortex formation in spin-up and of annihilation in spin-down measurements at temperatures below the hydrodynamic transition at 0.6 Tc where turbulence in the bulk volume becomes possible. Of central current interest are the very lowest temperatures at 0.2 Tc where the dynamic processes reflect on the properties of the T→0 limit.
