Abstract
In atom lithography the conventional roles played by light and matter are reversed: a mask of light is used to pattern a beam of neutral atoms. Up to now, atom lithography has yielded only structures periodic in one or two dimensions, with a typical period of λ/2 or even below [1]. Here we report the generation of various chromium structures with quadratic symmetry and the first realization of a superlattice structure using light forces [2].
