In quantum mechanics, what is the difference between velocity and phase velocity of matter wave? How can it also be that phase velocity of matter wave always exceeds the speed of light?
Wikipedia said:The variable v can either be taken to be the speed of the particle or the group velocity of the corresponding matter wave.
My essential question is, what is the difference between vp and v here? Isn't vp=ω/κ, the same idea as the ''PURE'' velocity of wave?
