Talk:Minimal coupling

Is this true? I think one gets higher multipole moments from the minimal coupling principle. Because one does a dipole-approximation to get the "E times r" or "A times p" hamiltonian out of the minimal-coupling hamiltonian. I understood that minimal accounts for the most simple introduction of the interaction which yields an gauge invariant hamiltonian. --31.18.25.138 (talk) 19:21, 23 December 2011 (UTC)[reply]

Quality issue

This article does not treat quantum mechanics and field theory. It should be rewritten or deleted. Aoosten (talk) 12:06, 16 May 2025 (UTC)[reply]

I disagree, minimal coupling is not necessarily a quantum concept. You can add more if you want.--ReyHahn (talk) 14:13, 16 May 2025 (UTC)[reply]
