Query: Monitoring the Dipole-Dipole Interaction via Quantum Jumps of Individual
  Atoms   The emission characteristics in the fluorescence of two laser-driven
dipole-dipole-interacting three level atoms is investigated. When the light
from both atoms is detected separately a correlation of the emission processes
is observed in dependence of the dipole-dipole interaction. This opens the
possibility to investigate the dipole-dipole interaction through the emission
behavior. We present Monte-Carlo simulations which are in good agreement with
the analytic solutions.
