    "abstract": "We analyze a method for serial writing of arbitrary two-dimensional patterns\nusing optical focusing of a collimated atomic beam. A spatial light modulator\nis used in a side illumination geometry to create a localized optical spot with\nsecondary maxima that are well separated from the central peak. Numerical\nsimulation of a lithography experiment using a magneto-optical trap as a source\nof cold Cs atoms, collimation and cooling in a magnetic guide, and optical\nfocusing predicts full width at half maximum pixel sizes of 110 x 110 nm and\nwriting times of about $20 \\rm ms$ per pixel.",
