All atomic motion is composed of phonons, and all properties of materials/molecules depend on atomic motion. People are learning how to control phonons, so we'll soon learn to control matter.

Explain how matter would be controlled in new, different, and innovative ways with phonons?

I'm so done with retards making up idiotic particles to explain everything.

Lmao, phonons are quite possibly more real than the elementary particles, since for a phonon you know 100% that there is a minimum quanta of energy that can be excited in a finite crystal and you dont have to come up with bullshit regularization. You know literally nothing about quantum fields.

True! I just want a little nectar from the gatekeepers. Do share.

Pulsed lasers, shockwaves, alloying, etc.

It's not a particle. Physicists liken them to particles because they interact with particles like photons due to their frequency.

Without phonons we wouldn't have superconductivity.

Just look up nonlinear phononics studies published in Nature within the past 5 years. There are many ways to control matter with phonons.

They're not particles, they're normal modes of vibration. Physicists liken them to particles because they interact with other particles like photons due to their frequency.

can you suggest a good book to learn crystal structures and space groups?

I know they study crystal growth in space (zero to low gravity environment) because they form perfectly in that and in the process of it they’re learning better ways of delivery for medicine with it somehow

It’s out of my league I just recall hearing it on nasa tv a few years ago and your comment mentioned both crystal and space

Phonons aren't fundamental particles, but sure, you can abuse field theory to make it work enough
