Doppler cooling to the Quantum limit
Doppler Quantum limit Atomic Physics single scattering events
2011/8/4
Abstract: Doppler cooling on a narrow transition is limited by the noise of single scattering events. It shows novel features, which are in sharp contrast with cooling on a broad transition, such as a...
Resolved-sideband cooling and measurement of a micromechanical oscillator close to the quantum limit
Resolved-sideband cooling measurement micromechanical oscillator quantum limit
2010/4/8
The observation of quantum phenomena in macroscopic mechanical oscillators has been a subject of interest since the inception of quantum mechanics. Prerequisite to this regime are both preparation of ...
Quantum limit of optical magnetometry in the presence of ac-Stark shifts
Quantum limit optical magnetometry presence ac-Stark shifts
2010/10/15
We analyze systematic (classical) and fundamental (quantum)limitations of the sensitivity of optical magnetometers resulting from ac-Stark shifts. We show that in contrast to absorption-based techniqu...
