Enthralling

The Experimental Evidence for Vortex Nucleation in 4Heone of the authors [.]. Recent developments of the model of vortex nucleation involving a vortex half-ring are assessed with an emphasis on the statistical properties of the critical velocity transition. The occurrence of collapses and multiple slips is then discussed in relation with the problem of

Experiments on Quantized Turbulence at mK Temperaturesvortices are created by a vibrating grid, and detected by their trapping of negative ions. Preliminary results suggest the existence of a temperature-independent vortex decay mechanism below . ~ 70 mK.
