For an [n-level system](n-level%20system) subject to an externally applied field we observe a periodic exchange in energy quanta between the external field and the system we refer to as _Rabi oscillations._ # Rabi Frequency # Nuclear magnetic resonance # Rabi oscillations in atomic systems ([... see more](Optical%20Rabi%20Oscillations.md)) #QuantumMechanics/QuantumDynamics #QuantumMechanics/QuantumDynamics/TwoLevelSystems #QuantumMechanics/QuantumDynamics/QuantumHarmonicOscillators
