title = "Dynamics of quantized vortices in a torsional oscillator under rotation: Proposed experiments in supersolid 4He",
abstract = "Recently there have been reports of superfluidity in solid 4He and possibly in other solids. One of the common features of these systems is their small superfluid density. This would imply a rather long three dimensional (3D) coherence length. Sub-monolayer superfluid 4He films condensed on 3D connected surfaces show 3D superfluid transitions, in some cases with a rather small 3D superfluid density and a long 3D coherence length, which implies a large 3D vortex core size. We have previously detected 3D vortex lines in a 3D superfluid made of a sub-monolayer 4He film condensed on the pore surface of large pore diameter porous glass, by measuring the energy dissipation in a torsional oscillator under rotation. We propose application of this method to the new supersolids.",
