Atomtronics & Superfluid Circuits

[sanman]

An atomic SQUID has been created from a superfluid circuit:

What are the applications of this?

If you could have a superfluid coil, then could it generate some kind of field, like the way an electric coil does?

Given that the rotation of massive bodies generates frame-dragging, then does the rotation or circular movement of even small amounts of matter also do this on a small scale?

Could frame-dragging effects somehow be channeled through a coil, analogous to the way that electromagnetic fields are combined through a helical coil?

You really shouldn't go off on a tangent like this, whereby you are trying to extrapolate something you barely know into a rather ridiculous situation.

Please note that in a SQUID, it is the phase difference in wavefunction that is predominately responsible for the effect. We don't have "rotation or circular movement" here in the real sense.

Ahh, so this is quantum fuzziness again, rather than real movement.

But still - what are the applications for it?

I remember an experiment done by Martin Tajmar in 2006 on "gravitomagnetism". He later did a related experiment using a superfluid:

In June 2008, Tajmar reported a new phenomenon suggesting that signals could be induced in a gyroscope resulting from a new property of rotating low-temperature helium. He also reported that because the rings in the experiment were accelerated pneumatically, and not with high acceleration, the earlier reported results could not be discounted.[7] His further research suggests the anomaly may indeed be coming from liquid helium in the setup.[8]

Does anyone have more information on this? What are the implications of it?
