Added Magnetic Loop VP operator #17

Closed ihateemoji closed 3 years ago

ihateemoji commented 3 years ago

Added the magnetic loop VP correction operator as per PRA Vol 58(2) Radiative Correction to the hyperfine-structure splitting of H-like systems by Sunnergren Persson et al. EQN (58).

I cannot exactly match Volotka's VP results for H-like 1s, I'll do more testing.

(I've accidentally created previous pull requests without the latest commit, I've closed that one)

I cannot find the reason behind the discrepancy between my results and Volotka's. I think I might be doing something wrong when converting the reduced matrix elements of my operator.
