Abstract

The correlated motion of two atoms trapped at distant positions in the field of a driven standing-wave high-Q optical resonator was investigated. It was found that for good trapping and low cavity losses the atomic motion becomes significantly correlated and the two particles oscillate in their wells with a 90° relative phase shift. It was observed that the cross-friction effect provides cooling of distant trapped clouds, as it creates correlation and leads to a fast thermalization of two distant particles without direct interaction. It was stated that the crossfriction prove vital for the implementaion of cooling of distant ensembles coupled by a far off-resonant cavity field.
