    "abstract": "We consider the exchange of spin and orbital angular momenta between a\ncircularly polarized Laguerre-Gaussian beam of light and a single atom trapped\nin a two-dimensional harmonic potential. The radiation field is treated\nclassically but the atomic center-of-mass motion is quantized. The spin and\norbital angular momenta of the field are individually conserved upon\nabsorption, and this results in the entanglement of the internal and external\ndegrees of freedom of the atom. We suggest applications of this entanglement in\nquantum information processing.",
