| Mar 20, 2017 at 2:57 | comment | added | WillO | @ACuriousMind has given you the answer, but in case the helps to clarify it: The components of angular momentum in the $x$ and $y$ directions do not commute, so they cannot both be well-defined at the same moment. Therefore they certainly cannot both be zero. | |

To put it differently, $L^2$ is the basically the Laplacian in spherical coordinates, but your functions $e^{im\varphi}$ are not eigenfunctions of the Laplacian. | |

| Feb 8, 2017 at 13:28 | comment | added | Phillip | I am relatively new to this field of physics, so i would prefer if you forgave me for any mistakes that i made regarding the quantum mechanical formalism. | |
| Feb 8, 2017 at 13:14 | comment | added | ACuriousMind♦ | "However, both values can only be the same if the components in the x and y direction are both equal to zero" - why? (Don't argue classically, show it in quantum mechanics!) | |
