Steady-state quantum interference in resonance
... We have found that steady-state quantum interference may cause complete cancellation in the total resonance fluorescence because we have restricted our attention to atoms having a single (non-degenerate) ground state. If we expand our treatment to include atoms having multiple ground states, the gen ...
