    "abstract": "The paper reports on the observation of a new type of instabilities in the\natomic cloud of a magneto-optical trap (MOT). They appear as large amplitude\nself-oscillations, either periodic or erratic, depending on the parameters. An\noriginal model taking into account the shadow effect and an homogeneous\ndistribution of the atoms in the cloud is developped. It allows us to show that\nthese instabilities originate on the one hand from an anomalous Hopf\nbifurcation, and on the other hand from the extreme sensitivity of the system\nto noise.",
