I was wondering if any of you knew about any recent studies on QHD and their results. Also I have been reading about superfluid, and wondering if it is possible to create artificial superfluid that would have productive uses ( I could really only think about self applying lubricant). Would this hypothetical superfluid be expensive or too unstable?

Superfluid liquid helium is fairly expensive to get and maintain — any material it lubricated would have to be at or below the LHe lambda point.

What is the LHe Lambada Point?

What is the LHe Lambada Point?

 

That's where liquid helium gets up and dances -the lambada

 

the LHe Lambda point is the temperature below which it behaves as a superfluid - hyperphysics super-fluidity
