    "abstract": "Ultracold atoms interacting with the optical modes of a high-Q optical ring\ncavity can synchronize their motion. The collective behavior makes the system\ninteresting for quantum computing applications. This paper is devoted to the\nstudy of the collective coupling. We report on the first observation of a\ncollective dynamics and on the realization of a laser, the gain mechanism of\nwhich is based on collective atomic recoil. We show that, if the atoms are\nsubject to a friction force, starting from an unordered distribution they\nspontaneously form a moving density grating. Furthermore, we demonstrate that a\n1D atomic density grating can be probed via Bragg scattering. By heterodyning\nthe Bragg-reflected light with a reference beam, we obtain detailed information\non phase shifts induced by the Bragg scattering process.",
