> In the experiments, the team created a superfluid helium film on a silicon chip.
> They then used a bright laser beam to draw energy out of waves on the surface of the superfluid, cooling them.
> In addition to laser cooling, the research team showed that combining superfluid with microphotonics allows extremely precise measurements of superfluid waves
Additionally, FWIU there are now inexpensive integrated lasers from which a laser cooling array could be built to enclose a QC sim
It would be interesting if it were used to cool laser sails, which might enable very high power levels for interstellar travel. This of course is not currently possible for multiple reasons.
