Abstract

The work reported here has been largely motivated by the recent interest in problem of dissipation or flux flow in the “Vortex Liquid” state of high Tc superconductors1. Early persistent current measurements for 4He in porous Vycor glass2 demonstrated that a possibly analogous state of dissipative flow exists for an extended temperature interval below the superfluid transition as observed in the limit of low frequency and amplitude. Additional motivation is found in the development of a new theoretical description for superfluid helium contained within a 3D connected porous medium in terms of the explicit dynamics of vortices of the superfluid system3. We will be interested in testing the predictions of such models for the regime of dissipative phase slip near the transition temperature as well as for thermally assisted phase slip at lower temperatures. A superfluid Helmholtz resonator has been developed for these measurements and our preliminary results are presented here.
