A general method for rotational microwave spectroscopy and control of polar molecular ions via direct microwave addressing is considered. Our method makes use of spatially varying ac Stark shifts, induced by far off-resonant, focused laser beams to a

We examine the time-dependent dynamics of ion crystals in radiofrequency traps. The problem of stable trapping of general three-dimensional crystals is considered and the validity of the pseudopotential approximation is discussed. We analytically der

We discuss the fabrication of various one and two-dimensional chromium nanostructures. A chromium atomic beam effusing out of a thermal oven is first transversally laser cooled. This well-collimated beam is then structured and focused by the optical

We have used neutral chromium atoms to write periodic nanometerscale structures in a direct way. We use the force exerted on the induced dipole of the atom in the intensity gradient of an optical standing light field to focus an atomic beam onto a su

Atom lithography provides a new technology that enables one to write directly nanometer scale structures onto a substrate in a parallel process. With this technique the trajectories of atoms are manipulated by light forces that efficiently focus the
