| Nov 18, 2012 at 13:59 | comment | added | Emilio Pisanty | This is because the group $SU(2)$ is essentially the same as the rotation group $SO(3)$ (more specifically, $SU(2)$ is a double cover of $SO(3)$, with two $SU(2)$ matrices, differing by a sign, corresponding to each rotation). The assertion then says that high-spin atoms have rotational symmetry, with the proper treatment of signs (i.e. possibly accumulating a global $-1$ after a $2\pi$ rotation). | |

| Nov 17, 2012 at 16:31 | comment | added | Nikolaj-K | You can apply a rotation to many objects, see en.wikipedia.org/wiki/…. If I understand your confusion correctly, this thread might clarify the situation, if you take into account that you have countable infinite representations of the rotation group. | |
