Light-matter interaction

AC Stark shifts and scattering rates: Clebsch-Gordan-weighted calculations for S→P and D→P transitions.

Overview

LMinteraction computes the interaction between a laser field and an atom: the AC Stark shifts for the ground-to-excited (S→P) and metastable-to-excited (D→P) transitions, and the off-resonant photon scattering rate.
