Mar 24, 2022 at 1:18 | comment | added | Eugene Stern | Thanks! I have to think about the $SO(4)$ action in a quiet room for a few minutes, but something like "the $n^2$-dimensional space is an irreducible representation of a larger set of symmetries" is totally the kind of answer I was hoping for. | |

Mar 22, 2022 at 13:53 | comment | added | Carlo Beenakker | the key problem I see is how to extend this argument for the hydrogen atom (one electron in a 1/r potential), to atoms containing multiple electrons (which will interact with the core as well as with themselves); this extension would then need to explain how the $n$ ordering rule becomes the $n+l$ ordering rule (and thus the sequence 2,8,18,32,... becomes 2,8,8,18,18,...); one of the papers I cite invokes the chain SO(4,2) $\rightarrow$ SO(3,2) $\rightarrow$ SO(3) $\otimes$ SO(2) to arrive at the $n+l$ rule, no idea if that makes sense or not. | |
