| Dec 21, 2023 at 7:07 | comment | added | Quillo | @knzhou and and Pato: this is exactly my point, maybe the question is not very clear. We all know that we can find the multipole moments, but where do we have to "place them"? I am aware that this may depend on what we want to minimise but this is never discussed (to the best of my very limited knowledge). I want to understand if there is a "standard" choice (because it's the mose useful) in the literature. | |

res. recom. qs can usually not be mixed wth an actual physics q

| Dec 21, 2023 at 3:20 | comment | added | Pato Galmarini | May be you want to minimize the total electrostatic energy $E^2$, and put the particle at the location of the potential minimum | |
| Dec 21, 2023 at 1:52 | comment | added | knzhou | Of course, it depends on what exactly you’re minimizing. If you want the field to fall off as quickly as possible, at very large radius, then you just place it to cancel the dipole moment as you said. If you have some other criterion in mind then the answer could be something else. | |
