We suggest a new interpretation of the Berkeley data on the dissipation of superflow in Josephson junctions in superfluid 3He-B. The measurements are well described by the following relation between the current through a junction and the pressure hea

Far from the lambda transition the critical flow of superfluid 4 He through a small orifice is determined by thermal nucleation of quantized vortices. Between 300 mK and 2 K linearly decreasing critical flow velocity has been observed earlier. As the

We present the numerical analysis of a Helmholtz resonator-based4He analog of the rf-SQUID. This device has been demonstrated to act as a sensitive gyrometer. The rotation is detected by its effect on the apparent critical velocity of helium superflo

We have determined the features of a universal energy barrier which mediates the thermal nucleation of quantized vortices. The barrier is deduced from measurements of the intrinsic phase slip critical velocity using both dc flow and single phase slip

Superfluids and superconductors are the only states of condensed matter that can be described by a single wavefunction, with a coherent quantum phase Φ. The mass flow in a superfluid can be described by classical hydrodynamics for small flow velocit

This update on the problem of vortex nucleation in superflows through micro-apertures follows the recent reviews of the subject by Zimmermann [1] and one of the authors [2]. Recent developments of the model of vortex nucleation involving a vortex hal

We report the first precision rotation measurements with a superfluid 3 He gyrometer. This device operates in the Josephson non-hysteretic regime. Its practical sensitivity could ultimately compare with those of ring lasers and atom interferometers.

We report here preliminary data from an experiment studying flow of superfluid helium through a slit orifice (of sub-micron width) very close to T λ . Critical supercurrent ( I c ) data are obtained from a step function drive to the diaphragm in a H
