    "abstract": "We study the motion of two atoms trapped at distant positions in the field of\na driven standing wave high-Q optical resonator. Even without any direct\natom-atom interaction the atoms are coupled through their position dependent\ninfluence on the intracavity field. For sufficiently good trapping and low\ncavity losses the atomic motion becomes significantly correlated and the two\nparticles oscillate in their wells preferentially with a 90 degrees relative\nphase shift. The onset of correlations seriously limits cavity cooling\nefficiency, raising the achievable temperature to the Doppler limit. The\nphysical origin of the correlation can be traced back to a cavity mediated\ncross-friction, i.e. a friction force on one particle depending on the velocity\nof the second particle. Choosing appropriate operating conditions allows for\nengineering these long range correlations. In addition this cross-friction\neffect can provide a basis for sympathetic cooling of distant trapped clouds.",
