Are phonons fundamental for advanced levitation technology?

advanced levitation technology

What "advanced levitation technology" are you referring to?

If we figure out more about phonons we might scale up the levitation abilities(?)

I couldn't say for sure, but the levitation itself doesn't seem to depend on any particularly quantum effects; it's just using sound to exert force on objects to counteract gravity. The quantum aspects of the sound don't seem to be important.

Levitation technology? I've no clue how you come to that idea.

Phonons are quasiparticles, i.e., quantum descriptions of vibrations of solids.

Interesting.

Are phonons fundamental for advanced levitation technology?

Not the levitation effect you were thinking about in post #3, but there is the Meissner effect which is some sort of magnetic levitation in the presence of a superconductor, and phonons are essential there for the superconductivity - look up the BCS theory.
