    "abstract": "A theoretical model is presented for the study of the dynamics of a cold\natomic cloud falling in the gravity \u0026#64257;eld in the presence of two crossing\ndipole guides. The cloud is split between the two branches of this laser guide,\nand we compare experimental measurements of the splitting ef\u0026#64257;ciency with\nsemiclassical simulations. We then explore the possibilities of optimization of\nthis beam splitter. Our numerical study also gives access to detailed\ninformation, such as the atom temperature after the splitting.",
