Main Question or Discussion Point
Can we do double slit experiment using ,let's say phonons.
phonons=quantized lattice vibrations.You'd need to discover them in nature first, then develop controlled means of emission and detection, or source existing ones, but I don't see why not.
So the only difference is phonon interference can never be projected on a scree at distance?The atom in the lattics vibrate and the collective mode is phonon. The wave on the lattices can have the interference, so it is possible to observe there interfernce, which can be thought as one kind of double slit experiment. Just the setup may be different dramatically from the setup to photon.
