Nonstationary dephasing of two level systems
– We investigate the influence of nonstationary 1/f noise, produced by interacting defects, on a quantum two-level system. Adopting a simple phenomenological model for this noise we describe exactly the corresponding dephasing in various regimes. The nonstationarity and pronounced non-Gaussian features of this noise induce new anomalous dephasing scenarii. Beyond a history-dependent critical co...
متن کاملNonstationary Stochastic Resonance
It is by now established that, remarkably, the addition of noise to a nonlinear system may sometimes facilitate, rather than hamper the detection of weak signals. This phenomenon, usually referred to as stochastic resonance, was originally associated with strictly periodic signals, but it was eventually shown to occur for stationary aperiodic signals as well. However, in several situations of p...
متن کاملResonance-fluorescence and absorption spectra of a two-level atom driven by a strong bichromatic field.
We identify discrepancies between two published predictions of the resonance fluorescence from a two-level atom driven by a strong bichromatic field @J. Opt. Soc. Am. B 8, 1163 ~1991! and Phys. Rev. A 48, 3092 ~1993!#. These discrepancies are shown to arise from subtleties in extracting the time-averaged resonance fluorescence from the expansions used to solve the optical Bloch equations. We co...
متن کاملObservation of phase-sensitive temporal correlations in the resonance fluorescence from two-level atoms.
We have made what we believe is the first observation of phase-dependent temporal correlations in the fluorescent field emitted by coherently driven two-level atoms in free space. We measured the temporal fluctuations of the fluorescent field when the resonant driving field was in phase and out of phase with the local-oscillator field.
متن کاملInfluence of atomic recoil on the spectrum of resonance fluorescence from a two-level atom.
We have continued our precision studies of laser induced stimulated resonance Raman interactions in a sodium atomic beam with emphasis on Ramsey's method of separated oscillatory fields. We observed Raman-Ramsey fringes for a field separation of up to 30 cm, and the data were consistent with theoretical predictions. We have also been investigating the performance of a clock based on this intera...
