In our latest publication, Glen Harris, Andreas Sawadsky, Yasmine Sfendla, Walter Wasserman, Warwick Bowen and Chris Baker suggest filling a slot waveguide with superfluid to create an ultralow-dissipation resonator for travelling acoustic and optical waves. If you are familiar with our work, that suggestion should not come as a surprise. What can we say? A layer of superfluid does make everything better. Superfluid, some might say, is the mayonnaise of quantum optics.
