Vacuum Rabi Oscillations: Time-Domain Cavity QED (2D)

This 2D companion trades the 3D version's frequency-domain transmission spectrum for the time-domain view of the same physics: RK4-integrated coupled atom-cavity amplitude equations show the excitation genuinely swapping back and forth between atom and cavity as damped vacuum Rabi oscillations in the strong-coupling regime, or decaying away in a single irreversible shot once cavity loss or atomic decay dominates — with the oscillation period measured straight off the simulated trace and checked against the closed-form splitting formula.
