"Single-atom optical clocks"
Abstract: With the availability of spectrally pure lasers and the ability to precisely measure optical frequencies, it appears the era of optical atomic clocks has begun. In one clock project at NIST we have used single trapped atomic ions because uncertainties in systematic effects are smallest, reaching a fractional error of f/f0 = 0.8 x 10-17. At this level, many effects, including those due to special and general relativity, must be calibrated and corrected for.
