Investigation of Unexpected Transport of Superfluid Helium Through Graphene

Abstract

We have observed unexpected transport of superfluid helium-4 in an apparatus designed to studysuperflow through nanoporous membranes. This small award was to help fund further experiments to pin down if this superflow was in fact through graphene membranes, or some artifact of the measurement system. In the end,we have been unable to make a concrete conclusion and this requires further study. The student involved in the work abandoned the experiment and the PI is currently looking for a way to continue the study.
