Abstract

Evidence has been reported for Josephson-type behaviour in the flow of superfluid helium-3 (3He) through an array of 4,225 apertures1,2 and for a metastable π-state at low temperature3. Here we show that an array of holes cannot be expected to act as a single weak link in such a system, and that these results can be explained without invoking the superfluid analogue of the much-debated ‘π-junction’ in other systems.
