Thanks for your answer. If photon is like wave, I expect after turning off the lamp to be able to detect again in it's first-detected place. Isn't it?

Consider a light source, like lamp, that radiates photons in vacuum. Can we detect a particular photon, moving in a specific direction, always at one point or the photon is localised and moves from one point to another? In other words, I would like to know that like free quantum particles...

What causes the phase difference between two non-orthogonal quantum states to increase? Or is any physical interpretation for phase difference between non-orthogonal quantum states?

I meant ##\hat{L}_z e^{im\phi}=m\hbar e^{im\phi}##, in classical view, represents the rotation around the z-axis with angular momentum ##m\hbar##. Since the particle is not localised, again by classical view, we expect the rotation occurs in all circles around the z-axis. Then, at greater ##r##...

Thanks again for your help! To build on what I mentioned in post #6, the case I had in mind was specifically a rotation around the ##z## axis.

For rotation around the z axis ##p## and ##r## are orthogonal, or at least non orthogonal components don't contribute.

Also in quantum, the time evolution of an eigenstate appears as phase coefficient, and it seems that the phase change to be related to the origin of time.

In quantum mechanics phase change, as a coefficient ##e^{i\theta}##, would not change the quantum state. I would like to know whether we have such a concept for classical systems.

Here, it is not ##[x,p_x]## but we have something for example like ##[x,p_y]=0##.

So, for a constant ##L_z=m\hbar## we expect that getting far from the ##z-##axis the linear momentum decreases.

On the contrary, I think the particular case ##l=0## is more understandable from classical view. It describes the particle at rest. However, the quantum particle is not localized at a particular point. We can find it everywhere with the same probability.

Angular momentum as generator of rotation in defined by ##L=r\times p##. However, none of the angular momentum wave functions depends on the ##r##. They only depend on the angles.

As far as I know, photoelectric field requires a threshold frequency that under this frequency the effect can't be observed.

Could you please send the link to this insight?

If I understood correctly, you mean that intensity is independent of frequency. Isn't it?
