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##...

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...

Something similar happens with waves in classical physics: the phase is determined by our choice of where we choose ##t=0##. I'm not...

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

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.

Intuitively: if r and v point in the same or opposite direction, L is zero. So only movement in the direction perpendicular to r...

On the contrary, I think the particular case ##l=0## is more understandable from classical view. It describes the particle at rest...

Inserting $$\mathbf{p}=-i\hbar \nabla$$ in formula of L, you will prove that L has no r dependence.

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

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?

There is no such thing as a photon in classical EM. It's not just that the frequency of the light is the key factor. The dislocated...
