Phytoplankton photosynthesis links global ocean biology and climate-driven fluctuations in the physical environment. These interactions are largely expressed through changes in phytoplankton physiolog...
Intensity-field correlation of single-atom resonance fluorescence
Intensity-field single-atom resonance fluorescence
font style='font-size:12px;'>
2010/4/9
We report measurements of an intensity-field correlation function of the resonance fluorescence of a single trapped Ba+ ion. Detection of a photon prepares the atom in its ground state and we observe ...
