“…In those studies we found that an atom's temporal response to a resonant PDF is essentially composed of just two components. On time scales long compared to a Rabi period, an adiabatic component manifests itself in the instantaneous frame of field-atom interactions as a figure-eight pattern of the Bloch-vector trajectory [4]. Additionally, there is a nonadiabatic component in the atom's temporal response that manifests itself as enhanced atomic population variations oscillating at the Rabi frequency, &>i, similar to the oscillations of a damped, driven harmonic oscillator with its resonant frequency at tdj.…”

We have examined the temporal evolution of a two-level atom in response to stochastic phase-fluctuating fields by applying perturbation theory to the optical Bloch equations written in the instantaneous frame. Our results show that the general nature of the atomic population variations is relatively simple, being composed of adiabatic and nonadiabatic components. The adiabatic response results from Fourier components of the phase variation below the system's Rabi frequency and is proportional to the product of the relatively slow phase variation and its first derivative. The nonadiabatic response has its maximum amplitude at the system's Rabi frequency, for which the atom behaves like a simple harmonic oscillator whose resonance frequency is the Rabi frequency. In this sense the atom acts as a tunable narrow-band filter.
