Observation of the Rabi-Resonance Spectrum
Abstract
By use of a double-resonance technique, a spectrum of Rabi resonances has been observed. These resonances are enhancements in the dynamic of a quantum system's population to rapid changes in the phase of a perturbing electromagnetic field. Theoretically, it is shown that the appearance of a spectrum, as opposed to a single Rabi resonance, is due to the fact that the phase of the field changes discretely by pi radians, rather than sinusoidally. In the presence of pi radian phase changes, the quantum system's dynamic response is found to be similar to a damped harmonic oscillator driven by a delta function force term. In this harmonic-oscillator approximation the Rabi- resonance spectrum arises naturally, resulting from a resonant enhancement of the atomic coherence.
