What's the underlying physical mechanism? The photon is absorbed and reemitted as two?

I guess one could draw the Feynman diagram for this interaction, but I don't think it makes a whole lot of sense to talk about a physical "mechanism". If the quantum numbers are conserved (energy, momentum, angular momentum, etc.) then it can just happen.

Can't say about the physics, but with my recent approximate knowledge of algebraic structures I think it has to mean that QM is an OK division algebra, meaning something is invertible. If the invertible thing is a matrix then it might have nice computational implications.
